Dear colleagues,
This is not strictly a R question, but more a methodology-related question.
I have the following linear model: Y = X\beta + e.
Pretty standard stuff, but additionally, X is square, symmetric circulant. So,
the LS estimate for \beta is given by just deconvolving Y with the in

union(g1, g2) evokes the wrong union(), which produces an error.

The standard answer is to use
> as.POSIXlt("2007-05-14") - as.POSIXlt("1950-01-01")
Time difference of 20952 days
If you want to ensure the time difference is in daily units, then
> difftime(as.POSIXlt("2007-05-14"),
as.POSIXlt("1950-01-01"), units = "days")
Time difference of 20

I think this is windows only. If you search the mailing list you can

Ozlem,
three ways of doing this, AFAIK:
1) save Excel data as tab-delimited values in a .txt file and please see
?read.table (you will need to set 'sep="\t"')
2) check the xlsReadWrite package out, very handy!
3) see the R-DCOM server and related software by Bayer and Neuwirth, but

Hi
it will partly depend on which format of dates you use but usually it is
as easy as

Time differences in days

When I perform a two-tailed sign test with the following simple syntax,
binom.test(59,100)
R returns a P-value (0.088) but nothing else. As I want the result for a
one-tailed test I take P/2 = 0.044). However, the journal to which I've
submitted my results requests the test statistics, not just
Hi Antonio,
You can't in the current version. However, you can in the next
version, which I hope to release very soon:
p <- ggplot(mtcars, aes(y=mpg, x=factor(cyl)))
p + geom_boxplot() # has outliers
p + geom_boxplot(shape=NA) # no outliers

Hello,
I'm very much a newbie in R and more so in tcltk so apologies if this
question is stupid. Basically I am trying to use the combobox example
found here:

What I want to do is in that example get fruitChoice as a variabl
Dear all,
I am currently facing a problem related to the spatial autocorrelation of
a sample of stations; these stations supply weekly data for a fixed
time-window during the year (namely, 4-6 months per year).
For this reason I'm trying to use the R package 'spdep' (specifically
Moran's I) in
Hi.
How can I suppress those red dots from ggboxplot output in package ggplot?
This is especially a nuisance when adding a jitter (as it is done in the end
of the package vignette).
Bests,
Antonio.

Hi all.
Consider the following example from ggplot vignette:
ggpoint( ggplot(tips, .~sex, ae=list(y=tip, x=total_bill)) )
You have one scatterplot per sex. With 'ggabline' I can add one or more
lines to each subplot at the same time.
How can I add different lines in each subplot?
Note that I have

All,
I guess the idea is identify the number of NAs na(r) in
particular row r, then calculate the 'original' row-sum ors(r) based on
the info on the set of non-missings in the previous row, i.e., na(r-1),
right?

Hi
there probably is not an easy out of box solution. Some use can be in rle
function e.g.
> apply(apply(ac,2,function(x) (is.na(x))),2, function(x)
rle(x)$values[1])
V1V2V3V4V5
FALSE FALSE FALSE TRUE TRUE
gives you columns which start with NA and

Hello
My dear friend the problem is not very heavy its very light, but you
have to assume somethings.
as you say that any new stock can come anytime and go anytime, further,
any time NA can come .
both statements are so close that it would be nearly impossible to know
which one is NA
