[Rd] Methods for format() are not consistent with NA values (PR#12385)
Hi!
Methods for format() are not consistent when applied to vectors
having NA values. Some methods encode NA values to "NA"
by default, while other do not. It would be much more easier to
write other functions if these functions would all behave
consistently.

[Rd] Bug in format.default(): na.encode does not have any effect for (PR#12318)
Hi!
If I use format() on numeric vector, na.encode argument does not have any e=
ffect. This
was reported before:
- https://stat.ethz.ch/pipermail/r-help/2007-October/143881.html
- http://tolstoy.newcastle.edu.au/R/e2/devel/06/09/0360.html
It works for other (say character) classes!
> format(c("a", NA), na.encode=3DTRUE)
[1] "a " "NA"
> format(c("a", NA), na.encode=3DFALSE)
[1] "a" NA
I explored this a bit and found out that format.default() uses prettyNum(.I=
nternal(format(...)))
for formatting the logical, numeric, complex, ... classes. Simple tests (se=
e bellow) show that
.Internal(format()) does not obey the na.encode argument.
## Encode NA as "NA"
> .Internal(format(x=3Dc(1, NA), trim=3DFALSE, digits=3DNULL, nsmall=3D0, w=
idth=3DNULL, adj=3D1, na.encode=3DTRUE, scientific=3DNA))
[1] " 1" "NA"
## Do not encode NA as "NA"
> .Internal(format(x=3Dc(1, NA), trim=3DFALSE, digits=3DNULL, nsmall=3D0, w=
idth=3DNULL, adj=3D1, na.encode=3DFALSE, scientific=3DNA))
[1] " 1" "NA"
## --> no effect
## Does prettyNum encode NA as "NA"
> prettyNum(c("1", NA))
[1] "1" NA
## --> not for character
> prettyNum(c(1, NA))
[1] "1" "NA"
## --> but it does for numeric

This problem is due to my specification in Rnw file i.e.
% \VignetteDepends{test}
If I remove this or remove just test and leave some other packages in it (that
are also in DESCRIPTION Depends field), then previously reported error in R CMD
check does not show up. It seems that I have not understood \VignetteDepends{}
properly. I thought that we need to specify all packages that are needed for
vignette to work.

[Rd] Problem with: Vignette dependencies (\VignetteDepends{} entries) must be contained in
Hello!
I have just discovered a possible bug or lack of my knowledge. The last
option is not so uncommon and I decided to ask here before flooding the
bugs repository.
Say I have a package test with vignette. Moving package directory to
some other name, say test2, fails R CMD check with
$ R CMD check test2
* checking for working latex ... OK
* using log directory '/home/ggorjan/programs/R/devel/test2.Rcheck'
* using R version 2.4.1 (2006-12-18)
* checking for file 'test2/DESCRIPTION' ... OK

* this is package 'test' version '0.1.0'
* checking package dependencies ... ERROR
Vignette dependencies not required:
test
Vignette dependencies (\VignetteDepends{} entries) must be contained in
the DESCRIPTION Depends/Suggests entries.
I got the same behaviour with recent R-devel (2007-04-18 r41219). Search
on R-{help,devel} and BioC mailing lists did not show any relevant info
for this error.
Search in R-devel sources reveals that above error string comes from
src/library/tools/R/{all.R,QC.R} - function print.check_package_depends,
which in turns uses info from function .check_package_depends and it
seems to me that relevant code is on lines 2436-2447.
I am attaching both test and test2 tarballs so anyone can test this easily.

Then sweave.bat from batchfiles depends on sh.exe as my Sweave.sh.
However, I guess that above line can also be done with MS command line.

However, I must say that my script provides several ways to get to the result e.g. if you use prosper you need to go via postscript, beamer behaves differently etc. There are now the following ways of LaTeX processing: Command and path Script option Used tools - texi2dvi - PS -tp, --texi2dvi2ps texi2dvi and dvips - PS to PDF -tld, --texi2dvi2ps2pdf texi2dvi, dvips and ps2pdf - PDF -td, --texi2dvi2pdf texi2dvi with pdf option - latex - PS -lp, --latex2dvi2ps hardcoded 'latex+co' + dvips - PS to PDF -lld, --latex2dvi2ps2pdf hardcoded 'latex+co' + dvips - pdflatex - PDF -ld, --latex2pdf hardcoded 'latex+co' + dvips > To install sweave.bat you must place sweave.bat (and Rcmd.bat) both > from this batchfiles distribution anywhere in your path.

As I stated I am not sure how Rcmd works, but Sweave in SVN is a shell script as well as Rcmd! How does it become an exe file?

[Rd] Sweave.sh shell script on CRAN
Dear developeRs,
Martin Maechler has suggested that I resend this email to R-devel
instead to R-packages for further comments and potential availability
for Windows.
--
I have uploaded my Sweave (bash) shell script on CRAN. It is available at
http://cran.r-project.org/contrib/extra/scripts/
In short this script runs Sweave on given Rnw file(s) and post process
produced tex file(s) with LaTeX and friends directly from command line.
It has quite a rich set of command line options to mainly ease the LaTeX
compilation.
Please do not hesitate to contact me in case you find errors or have
suggestions and/or code contributions. I am particularly, interested in
making this script work under Windows.
--
I do not have any experience with use of (bash) shell scripts under
Windows. Sweave.sh can be used with Cygwin, but I am not sure how to use
shell script without Cygwin. I noticed that some "scripts" in R*/bin
directory on our Windows machine are perl (build, check, INSTALL, ...)
and shell (Rd2dvi.sh, Stangle.sh, Sweave.sh, ...) scripts. This
therefore means that R ships also perl and shell interpreter or am I
missing something?
Thanks!

Yep, that is what I wanted.
setMethod(f="length", signature(x=c("myClass1", "myClass2"))

[Rd] Same method for more than one class
Hi,
when defining method (I used length bellow just for the simplicity) for
myClass (S4 class) I use
setMethod(f="length", signature(x="myClass"),
def=function(x) {
cat("works")
})
If I have myClass1 and myClass2 and mentioned method, which is not the
default one, applies to both classes I have to write two setMethod()
statements. Would it be possible to use
signature(x=c("myClass1", "myClass2"))
Currently it issues an error
setClass(Class="myClass1", representation=representation(x="integer"))
setClass(Class="myClass2", representation=representation(x="integer"))
setMethod(f="length", signature(x="myClass1"),
def=function(x) {
cat("works")
})
## OK.
setMethod(f="length", signature(x=c("myClass1", "myClass1")),
def=function(x) {
cat("works")
})
Error in signature(x = c("myClass1", "myClass1")) :
bad class specified for element 1 (should be a single character string)

[Rd] Registration of native routines
Dear R developers,
I am working on registration of native C and FORTRAN routines and have
encountered "inconsistencies" about this issue. I am referring to
"Registering native routines" section of R-ext manual.
*(DL_FUNC), &F77_SUB, &F77_SYMBOL
On line 5108 of R-ext.texi the array for method myCall is defined as
{"myCall", &myCall, 3},
but looking at examples in src/library/stats/src/init.c I notice
addition of (DL_FUNC) i.e. upper definition would be
{"myCall", (DL_FUNC) &myCall, 3},
This probably shows my poor knowledge of C, but what is the role of
(DL_FUNC)? Looking around the code I notice that DL_FUNC is used also in
other places. IMHO I would suggest that (DL_FUNC) is also "mentioned" in
the manual.
Additionally, what is the role of &F77_SUB() in registration of FORTRAN
subroutines i.e. the following line is one example from
src/library/stats/src/init.c.
{"lowesw", (DL_FUNC) &F77_SUB(lowesw), 4}
src/main/registration.c for example uses &F77_SYMBOL() instead of
&F77_SUB(). Poking around the source I see that this is related to _. I
would again suggest to add this to the manual.
*Type and style field
For .C() and .Fortran() manual says that registration array can also
hold type and style fields. It is shown how type field should look like,
but nothing usable is said about style except
Typically, one omits this information in the registration
data.
Why would one omit this if
The purpose is to allow @R{} to transfer values more
efficiently across the R-C/FORTRAN interface by avoiding copying values
when it is not necessary.?
Thank you!

OK. Is there some way to test which package is being used i.e. the
"standard" or enhanced one? Or to paraphrase this differently. Are there
any proposals how "conditional suggest" could be done?

I might have understood Enhances field wrongly but imagine this
situation. I have a package A and if I can use package B I would like to
use it otherwise try with "my own" solution. I thought that Enhances
fields is exactly for such situation. How should I check if package B is
available? I used
if(require(B)) {
someSuperDuperFuncFromPkgB()
} else {
myOwnStuff()
}
But R CMD check complains.
I have encountered this with R2WinBUGS. This package helps calling
WinBUGS from R. It can also use OpenBUGS via BRugs, but BRugs is
available only for Windows. Therefore, one can not do any QC under
Linux. I thought to provide ability to call OpenBUGS via the same way
WinBUGS is called and then to put BRugs in Enhances field. But R CMD
check complained about use of require() for a package that is in
Enhanced field.

See the information on DESCRIPTION files in the chapter 'Creating R

I have require(code) somewhere in the code. Is this OK or is R CMD check
to stringent in case of enhances field - I get no warning if that
package is in depends or suggests fields?
After a short look into src/library/tools/R/QC.R I think that the
following might be the solution. I did not do any other testing than
with my package, where R CMD check (R with proposed change) passed
without warnings.

[Rd] c() for factors
Dear R-core!
I have written a function mapLevels() to map levels of a factor. It can
produce a map (internally a list) of factor levels and internal integer
codes. I call this integer levelsMap. There is also character levelsMap,
but not of importance at this moment. I found out that it was quite
straightforward to write c() method for factors with use of mapLevels()
and Iam asking here if there is any interest to include this into base R.
In base R c() on two factors coerces to internal integer codes
> f1 <- factor(c("A", "B"))
> f2 <- factor(c("A", "C"))
> f1
[1] A B
Levels: A B
> f2
[1] A C
Levels: A C
> c(f1, f2)
[1] 1 2 1 2
or character vector if one of arguments is character
c(as.character(f1), f2)
[1] "A" "B" "1" "2"
this is OK, but not really wanted by the user. Code bellow show my
implementation of c.factor().
For the moment mapLevels() and c.factor() live in gdata package (from
version 2.3.1) - it has ben submitted to CRAN last night.
> install.packages("gdata")
> library(gdata)
## c.factor is not exported
> gdata:::c.factor(f1, f2)
[1] A B A C
Levels: A B C
> gdata:::c.factor(as.character(f1), f2)
[1] A B A C
Levels: A B C
> gdata:::c.factor(f1, as.character(f2))
[1] A B A C
Levels: A B C
> gdata:::c.factor(as.integer(f1), f2)
Error in mapLevels.default(X[[1]], ...) : mapLevels can only be used on
“factor” and “character” atomic 'x'
As can be seen characters are handled in the same way as factors. Does
anyone see any value in this?

I have tried with S4 class system and I would appreciate any help here. I was hoping that I would be able to include instance of my class into a data.frame. However, I encounter problems. Simple definition of class could be setClass(Class="composition", representation=representation(ratios="matrix")) n <- 2 k <- 3 x <- new(Class="composition", ratios=matrix(data=rep(x=1/3, times=n*k), nrow=n, ncol=k)) x An object of class "composition" Slot "ratios": [,1] [,2] [,3] [1,] 0.333 0.333 0.333 [2,] 0.333 0.333 0.333 tmp <- data.frame(id=1:2) tmp$comp <- x Error: object is not subsettable As I understand this, my problem is that x is of length 1 as the following works tmp$comp <- c(x, x) although I am not able to print tmp now tmp Error in unlist(x, recursive, use.names) : argument not a list but this is expected as I (probably) need show/print method for this.

That is a very nice compromise! No need for [1, ], due to nrow=1.

I fully agree here, but I kind of lack this directly in read.fwf. I hope
that someone from R-core is also listening to this ;)

[Rd] Wish: change behaviour of header in read.fwf (PR#9252)
Hello!
In my opinion read.fwf()'s behaviour of header is not really useful. Say
I have the following data:
col1 col2 col3
123 123 123
a b
123412 1234
65.4 4.5
Now if I want to read this data into R I can not use read.table due to
missing fields.
read.table(file="test.txt")
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,
na.strings, :
line 3 did not have 3 elements
However, read.fwf() can help me.
read.fwf(file="test.txt", widths=c(5, 6, 5))
V1 V2V3
1 col1 col2 col3
2 123123123
3a b
4 1234 12 1234
565.44.5
Upps, I need to specify header and help page says that header fields
must be separated by sep. sep part of help page says
sep: character; the separator used internally; should be a
character that does not occur in the file (except in the
header).
This is quite limiting because I never know in advance which characters
do not occur in a datafile and if I do, I have to properly modify
header in the file before import. Naive use of read.fwf returns an error
read.fwf(file="test.txt", widths=c(5, 6, 5), header=TRUE, sep=" ")
Error in read.table(file = FILE, header = header, sep = sep, as.is =
as.is, :
more columns than column names
read.fwf(file="test.txt", widths=c(5, 6, 5), header=TRUE, sep=" ")
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,
na.strings, :
invalid 'sep' value: must be one byte
I get lost in reading source of read.fwf, but I think that the following
idea should be easy to implement and it would be also similar to
read.table behaviour.
if(header) {
## sep is from read.fwf call
header <- unlist(strsplit(readLines(con=file, n=1), split=sep))
}
...
## tweaks related to issues with length(header), row.names, ncol(), ...
read.table(..., col.names=header, ...)
I know that FWF is not used much these days, but I would find proposed
change really useful.

[Rd] na.encode in format for Date and POSIXt classes
Hello!
na.encode does not have any effect on format of NA values of Date and
POSIXct (POSIXlt?) "atomic" classes in a data.frame. Here is the example
(the same in R 2.3.1 and 2.5.0 (2006-09-19 r39409)):
testData <- data.frame(num=c(NA, 2.6),
int=c(1, NA),
fac=factor(c(NA, "abc")),
cha=c("a", NA),
dat=as.Date(c("1900-1-1", NA)),
POS=as.POSIXct(strptime(c("1900-1-1 01:01:01",
NA),
format="%Y-%m-%d %H:%M:%S")))
testData$cha <- as.character(testData$cha)
testData
num int fac chadat POS
1 NA 1 a 1900-01-01 1900-01-01 01:01:01
2 2.6 NA abc
format(testData)
num int fac chadat POS
1 NA 1 NA a 1900-01-01 1900-01-01 01:01:01
2 2.6 NA abc NA
format(testData, na.encode=FALSE)
num int fac chadat POS
1 NA 1 a 1900-01-01 1900-01-01 01:01:01
2 2.6 NA abc
format(testData, na.encode=TRUE)
num int fac chadat POS
1 NA 1 NA a 1900-01-01 1900-01-01 01:01:01
2 2.6 NA abc NA
After a brief look into format.data.frame, format.POSIXct and
format.POSIXlt I notice that na.encode is not used at all in (last line
of format.POSIXlt)
.Internal(format.POSIXlt(x, format, usetz))
but I get lost from this point forward. I guess that the same applies to
format.Date as this coerces Date to POSIXlt before formatting.
Additionally, I would suggest change in format help page for argument
na.encode. It says now
na.encode: logical: should 'NA' strings be encoded?
If I am not wrong, this applies only to non-numeric columns. Something
like the following might be more accurate:
na.encode: logical: should 'NA' strings be encoded (applies only to
non-numeric)?

This is the behaviour in R-devel. > object.size(1000) [1] 32 > c(object.size(1000), object.size(1:1000), object.size(1:100)) [1] 324024 424 > options(humanReadable=TRUE) > object.size(1000) [1] 32 B > c(object.size(1000), object.size(1:1000), object.size(1:100)) [1] 32 B 4 kB 4 MB I am not very satisfied with the class approach I have taken as a lot of functions in R drop class attribute, say > sort(c(object.size(1:1000), object.size(1000)) ) [1] 32 4024 Is it possible to bypass this without writing special methods for "byte" class. I would appreciate any comments, suggestion. Thanks!

[Rd] Error: package/namespace load failed for 'fortunes'
Hello!
I have the following R code in my .Rprofile file - just for fun.
library(fortunes)
fortune()
detach("package:fortunes")
This works nicely in R 2.3.1, but it throws the following error under
latest R-devel:
...
...
Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.
Error in rbind(rval, read.table(file, header = TRUE, sep = ";", quote =
"\"", :
could not find function "read.table"
Error: .onLoad failed in 'loadNamespace' for 'fortunes'
Error: package/namespace load failed for 'fortunes'
>
If I start R-devel with empty .Rprofile I am able to issue above R code
without problems. Is this caused by move of read.table() to utils package?

Thank you for this clarifications. As indicated ISBN is not changing
very often and I can live with couple of BibTeX entries for R.
Thanks!

[Rd] R Citation through time
Hello!
I keep my local bib file and up to now I had entry
@Manual{R:2003,
title = {R: A Language and Environment for Statistical Computing},
author = {{R Development Core Team}},
organization = {R Foundation for Statistical Computing},
address = {Vienna, Austria},
year = {2005},
note = {{ISBN} 3-900051-00-3},
url = {http://www.R-project.org},
}
With recent versions ISBN changed to 3-900051-07-0. Now I wonder if
there is any canonical way to refer to R without the need to change R
entry over and over. It would probably be the best just to add new entry
for "new version" for R. Now the question is what is new version or when
does ISBN number change?
Thanks.

I agree that there is no need for attributes to be always in the same
order as this is tedious to achieve as you noted above, but identical()
seems to care about this.

Which internal storage mechanism are you talking about here?

Hello!
I was doing some tests with identical() and found out that [<-.POSIXlt
method changes order of attributes. This example shows that:
x <- strptime("1900-1-1", format="%Y-%m-%d")
x <- c(x)
y <- c(x, x+1)
x1 <- x
y1 <- y
attributes(x)
$names
[1] "sec" "min" "hour" "mday" "mon" "year" "wday" "yday" "isdst"
$class
[1] "POSIXt" "POSIXlt"
$tzone
[1] "" "CET" "CEST"
identical(attributes(x), attributes(y))
TRUE
x[1] <- NA
attributes(x)
$names
[1] "sec" "min" "hour" "mday" "mon" "year" "wday" "yday" "isdst"
$tzone
[1] "" "CET" "CEST"
$class
[1] "POSIXt" "POSIXlt"
y[1] <- NA
attributes(y)
$names
[1] "sec" "min" "hour" "mday" "mon" "year" "wday" "yday" "isdst"
$tzone
[1] "" "CET" "CEST"
$class
[1] "POSIXt" "POSIXlt"
identical(attributes(x), attributes(x1))
FALSE
identical(attributes(y), attributes(y1))
FALSE
This can be solved with either:

Re: [Rd] Wish: keep names in mapply() result
Hello,
Charles Berry sent me (off-list) his proposal, which I find better
(after slight modification) than mine. I would say that proposed changes
make mapply even more consistent with (some) *apply* funcs in terms of
names. Patches to mapply.R and mapply.Rd are attached. I have runned
make check-all and it seems that there are no problems with this change.
I hope R core will find this worth to apply.
New behaviour without first ... as character:
l <- list(a=1, b=2)
k <- list(1)
mapply(FUN="+", l, k)
a b
2 3
mapply(FUN="+", l, k, USE.NAMES=FALSE)
[1] 2 3
mapply(FUN="+", l, k, SIMPLIFY=FALSE)
$a
[1] 2
$b
[1] 3
mapply(FUN="+", l, k, SIMPLIFY=FALSE, USE.NAMES=FALSE)
[[1]]
[1] 2
[[2]]
[1] 3
New behaviour with first ... as character _with_ names:
l <- c("1", "2")
names(l) <- c("a", "b")
mapply(FUN="paste", l, k)
a b
"1 1" "2 1"
mapply(FUN="paste", l, k, USE.NAMES=FALSE)
[1] "1 1" "2 1"
mapply(FUN="paste", l, k, SIMPLIFY=FALSE)
$a
[1] "1 1"
$b
[1] "2 1"

[Rd] Wish: keep names in mapply() result
Hello!
I have noticed that mapply() drops names in R 2.3.1 as well as in
r-devel. Here is a simple example:
l <- list(a=1, b=2)
k <- list(1)
mapply(FUN="+", l, k)
[1] 2 3
mapply(FUN="+", l, k, SIMPLIFY=FALSE)
[[1]]
[1] 2
[[2]]
[1] 3
Help page does not indicate that this should happen. Argument USE.NAMES
does not have any effect here as it used only in a bit special
situation: "If the first ... argument is character and the result does
not already have names, use it as the names." But result is always
without names as shown above. Did I miss any peculiarities?
This is not consistent with lapply, which keeps names i.e.
lapply(l, "+", 1)
$a
[1] 2
$b
[1] 3
I have attached and copied (at the end) patch proposal against SVN that
adds names back to the result if x had it (only R as my C is ...). This
way it would also be consistent with lapply. make check-all seems to be
happy with changes. Now we get:
mapply(FUN="+", l, k)
a b
2 3
mapply(FUN="+", l, k, SIMPLIFY=FALSE)
$a
[1] 2
$b
[1] 3
And if we had "character" (with some variations) for first ... then:
l <- list(a="1", b="2")
mapply(FUN="paste", l, k)
a b
"1 1" "2 1"
l <- list("1", "2")
mapply(FUN="paste", l, k)
[1] "1 1" "2 1"
l <- c("1", "2")
mapply(FUN="paste", l, k)

OK, I did not know that and I appologize for making noise on the list
for this. However, I wonder how many people know this? It is fine to
have some short-hands (as IMHO, RTFM, etc. in e-mails), but these can be
an obstacle for exact understanding of the documentation, specially for
non-english users.

[Rd] Error in options(...) : invalid continue parameter
Hello!
It seems that prompt and continue argument of options() must be at least
of length one i.e.
> options(prompt="")
Error in options(...) : prompt parameter invalid
> options(prompt=" ")
# bla, bla, ...
> options(prompt="> ")
> # bla, bla, ...
> options(continue="")
Error in options(...) : invalid continue parameter
> options(continue=" ")
> ls(

This could be properly documented as shown bellow. I do not think that
it is worth bothering with modifying the code to allow empty prompt and
continue argument.
Cheers!

[Rd] Wishlist: multiple classes in \method{}{} (Rd markup) (PR#9135)
Hello!
I wish that one could use
\method{myMethod}{classA, classB}(x, arg1, arg2, arg3, ...)
instead of
\method{myMethod}{classA}(x, arg1, arg2, arg3, ...)
\method{myMethod}{classB}(x, arg1, arg2, arg3, ...)
when methods for both classA and classB have same set of arguments. This
way there would be a line or two less markup in Rd file as well as in
produced help page - one with note for both (or several classes) is more
than enough. This might also ease reading of help pages.
Thank you very much for such a great software!

I appologize for not reading the latest documentation - there was no word about droping names in 2.3.1. However, I do wonder why simple fix (as shown in previous mail) is not OK. Afterall, there is considerable variability on what unique methods drop and what they preserve. Say: * factor - keep all levels as in x * data.frame - keep rownames (which are "needed" by default anyway) * matrix - keep rownames as well as colnames and I am perfectly fine with all these, I just wonder why names should be dropped if x is atomic and not (rownames and colnames) if x is a matrix, array or data.frame. Did I miss something or does addition of names back to atomic x break existing code?

[Rd] unique.default() drops names (PR#9130)
Hello!
unique on a vector or list drops names, while it does not in case of
data.frames and matrix - rownames and colnames here, but they are
intuitively the same as names. The following code shows this effect:
vecTest <- c("A", "D", "B", "D", "A")
names(vecTest) <- paste("name", vecTest, sep="")
unique(vecTest)
listTest <- as.list(vecTest)
unique(listTest)
dfTest <- data.frame(vecTest)
unique(dfTest)
matTest <- as.matrix(vecTest)
colnames(matTest) <- "col1"
unique(matTest)
I did not bump into .Internal(unique(x)), but the following change
(diff to latest SVN version) to unique.default seems to work. Is this
acceptable?

I think that having generic for POSIXlt would be more natural than default length, which is (as stated by Gabor) always 9.

Here is the example: n <- 50 x <- runif(n=n) y1 <- 2 * x + rnorm(n=n) y2 <- 5 * x + rnorm(n=n) y2[sample(1:n, size=5)] <- NA y <- cbind(y1, y2) fit <- lm(y1 ~ 1, na.action="na.exclude") summary(fit) ## Goes ok here fit <- lm(y2 ~ 1, na.action="na.exclude") summary(fit) ## But fails if we use matrix of response variables fit <- lm(y ~ 1, na.action="na.exclude") summary(fit) ## Response y1 : ## ## Call: ## lm(formula = y1 ~ 1, na.action = "na.exclude") ## ## Residuals: ## Error in quantile.default(resid) : missing values and NaN's not allowed if 'na.rm' is FALSE Am I doing something wrong here? -- Btw. man page of lm says (in the begining of the details): "A typical model has the form 'response ~ terms' where 'response' is the (numeric) response vector ..." ^^^^^^ Should not this part say that repsponse can also be a matrix?

I agree, but I wanted to learn ... argument in a more general way. That
was just an example - not a good one as you have showed.

Actually it is not OK. Bellow is simplified example that shows, what I
would like to do:
foo1 <- function(x, ...)

[Rd] Test for argument in ...
Hello!
Say I have a function foo1, which has argument ... to pass various
arguments to foo2 i.e.
foo1 <- function(x, ...)
{
foo2(x, ...)
}
Say that foo2 accepts argument arg1 and I would like to do the following:
- if foo1 is called as foo1(x) then I would like to assign some value to
arg1 inside foo1 before calling foo2
arg1 <- "some value"
foo2(x, arg1=arg1)
- if foo1 is called foo1(arg1="some other value") do not assign some
value to arg1 and call foo2
foo2(arg1=arg1)
However, I am not able to do this since I do not know how to test/check
if arg1 was given in foo1. Is it possible to test whether some argument
was passed in "..." i.e. something like
foo1 <- function(x, ...)
{
if(testForArgumentInThreeDots(arg1)) arg1 <- "some value"
foo2(x, arg1=arg1, ...)
}
Thanks!

[Rd] Wish/suggestion: add output of citation() to package "manuals" (PR#9009)
Dear R core, influenced by recent panel discussion in Vienna I think that it would be nice to add package specific output of citation() function to package reference manuals. I think that apropriate place would be just after fields from DESCRIPTION file. This will be OK for CRAN, but not for locally installed packages as there is not reference manual there (at least on my linux box) - why is this the case? Perhaps output of citation() could be added to package specific help page i.e. to mypackage.package.Rd file. The same could be done with R's manuals. I know that there is an entry in FAQ on this and that there is a note after launching R, but questions about apropriate reference on R-help list are quite frequent. Perhaps this is so due to the habit that one looks into the paper/book/manual about relevant information for reference. -- Lep pozdrav / With regards, Gregor Gorjanc -- University of Ljubljana PhD student Biotechnical Faculty Zootechnical Department URI: http://www.bfro.uni-lj.si/MR/ggorjan Groblje 3 mail: gregor.gorjanc bfro.uni-lj.si SI-1230 Domzale tel: +386 (0)1 72 17 861 Slovenia, Europefax: +386 (0)1 72 17 888 -- "One must learn by doing the thing; for though you think you know it, you have no certainty until you try."

Ben, you confused read.csv and read.csv2. Separator in read.csv is ",", while it is ";" in read.csv2.

Re: [Rd] levels for list and data.frame
oops, this does not pass R CMD check. I will have to read manuals a bit
more.
...
* checking S3 generic/method consistency ... WARNING
levels:
function(x, ...)
levels.list:
function(x, drop)
levels:
function(x, ...)
levels.data.frame:
function(x, drop)
...
Anyway, I would like to ask what is the "opinion" about writing methods
for classes as list and data.frame. Methods for this might not be as
simple as for numeric, character, factor and it would be nice that there
would be some guidelines for at least:
- what should be the "general" output i.e. list or something else - I
understand that it is hard to say in advance, but a common policy might
not hurt
- what to do if a method for a list or data.frame can not be applied to
each entry/column

[Rd] levels for list and data.frame
Hello!
Does R core find the following pacth usefull - I created methods for
levels for list and data.frame, which can be usefull to get a list of
levels for entries in a list or columns in a data.frame. Patch is
attached and shown bellow example
# Example

> tmp$a <- factor(letters[1:10])
> tmp$b <- factor(letters[5:14])
> tmp$c <- 1:10

> tmp2 <- list()
> tmp2$"1" <- tmp
> tmp2$"2" <- tmp1
> str(tmp2)

I find particulary usefull the list approach. Here is the example from
levels help page. I like this approach, since you can modify list and
apply it to a factor via levels.
## we can add levels this way:
f <- factor(c("a","b"))
levels(f) <- c("c", "a", "b")
f
f <- factor(c("a","b"))
levels(f) <- list(C="C", A="a", B="b")
f
I was playing around this last week and wrote a simple function[1],
which can save you some work in getting such a list from a factor. Is R
core interested in it?

[Rd] Internal codes of the factor
Hello! I am writing some functions and I repeatedly acces internal factor codes. I figured out that internal codes are 1:n where 1 represents 1st level, 2 2nd level etc. This is not documented and I wonder if this is on purpose and subject to change or would be a good idea to add this to documentation for factor?

I understand, however it would be really nice to have some guideline so
that developers would write more or less similar code. I had a problem
with one such functions, since it stopped if parameters values were out
of parameter space. I used that function in optim() and it was
annoyingly stopping the optimization. It was not much to change the
function to return NaN (this could be as well NA as you have pointed
out), but it would be nice that this would be the default.
