 The latest version of R for OSX available on CRAN (R-2.1.0a.dmg)  
 reports itself as Version 1.11 (1.11).  This is actually the  
 version of the Macintosh GUI and not the underlying R framework  
 (which is 2.1.0) but it is found where traditional mac users are  
 going to look to find the version information: R - About R.
 
 I think I may have also stumbled across a tiny little bug in .C.  I  
 forgot to capitalize Hello:
 
   .C(hello, as.integer(5))
 Error in .C(hello, as.integer(5)) : C function name not in load  
 table

No, it is intended to say C or Fortran, AFAICS.

Uwe Ligges

 I think it should say 'hello function name not in load table'.

Hi everybody,
I'm working on Mac OS X and R-2.1.0 (by the way, sorry for the multiple 
emails last time, had a technical problem, and thanks for the 
constructive comments.)
I have a .R function which calls a .C function.  The R function's name is 
K_MEANSR.R and the other is K_MEANSC.C.
I compile it with 'R CMD SHLIB K_MEANSC.C' in the terminal.  I get both 
.so and .o files.
I use the function
   dyn.load ('K_MEANSC.so')
with no error.  We can, I believe, see here that it is loaded:

   getLoadedDLLs()

I then source the R code:
   source(file.choose())
Construct a matrix that I will use for the analysis:
   tab-c(1,1,3,4,6,6,3,5,7,67,5,6,65,3,5,1,5,42,3,567,6,4,7,7)
   tab-matrix(tab,6,4)
And try to use the function:
   K_MEANSR(tab,centers=c(2,4))
[1] AA
[1] AAA
[1] A
[1] B
Error in .C(K_MEANSC, xrows = as.integer(xrows), xcols = 
as.integer(xcols),  :
  C function name not in load table
Everything that is printed on the screen is correct, but why does it says 
that 'K_MEANSC' function is not in load table??? It then just stops at 
that stage of the .R function.

What does your declaration of the function look like in the K_MEANSC.C 
file?  R needs to know the name of the exported function, not the name of 
the .so file.

Duncan Murdoch
 
 
 It's in the form:
 
 K_MEANSC- function(arguments...)
 {
 
 }
 So the name of my .C function is also K_MEANSC...

No, you misunderstood.  That's R code; I was asking about the C language 
code that you want .C(K_MEANSC, xrows = as.integer(xrows) ... to call.

[Rd] Brewer colours

2005-07-07 Thread Peter Kleiweg

Anyone who is interested in using optimal colour palettes should
look at the work of Cindy Brewer: www.colorbrewer.org

I have written code to use her colour schemes in R. It is
included below. Perhaps someone may find this interesting enough
to work into a package.

Included also is a function showpalette, which was posted here a
while back. I don't remember who wrote it.

I have copied all the palettes from colorbrewer with the maximum
number of colours (which varies per palette). I have written a
function that translates these colours directly to rgb, or
through interpolation if you need a larger (or smaller) palette.
If you need a smaller palette, you may have to go to
www.colorbrewer.org for optimal results.

There are three types of palettes:
- Sequential, from minimal (light) to maximal (dark).
  There is no white in the original palettes. I added white.
- Diverging, from one extreme (dark) through light to another
  extreme (dark, another colour).
- Qualitative, no particular order.

To view a palette with the original colours:

showpalette(brewer2rgb(brewerSequential.YlGnBl))

To view the same palette, interpolated to another number of
colours:

showpalette(brewer2rgb(brewerSequential.YlGnBl, 19))

Notes:

  1. Interpolating Qualitative palettes does not work. You can't
 get more colours. If you need less, go to www.colorbrewer.org

  2. The palettes are tested to consist of colours that are
 optimally distinguishable to the human eye. Not all
 palettes may be useful in all circumstances or media. See
 www.colorbrewer.org for specs per palette and per number of
 colours. Interpolating to more colours will loose the
 distinction.

 Do you mean something like:

Now I feel silly. Well, it was a nice exercise.

Re: [Rd] write.csv (PR#7992)

This topic already came up about a week ago on R-devel
 Subject: write.csv suggestion

 [ too bad that R-devel is not available via  RSiteSearch() ...
{I could send you the back archives, Jon, if you are interested} ]

There, Brian Ripley, explained why this is not a bug, since
it works as documented, CSV files are well defined entities
and you can always use write.table() if you want to be flexible.

Brian also changed things for R-devel {to be R 2.2.x} such that
its help page, see
   http://stat.ethz.ch/R-manual/R-devel/library/base/html/write.table.html ,
now  has

 Usage:
. . . .

  write.csv(...)
  write.csv2(...)

 . . . .


 Arguments:
. . . .

  ...: arguments to 'write.table': 'col.names', 'sep', 'dec' and
   'qmethod' cannot be altered. 

which should make the intention of the write.csv*() wrapper
functions a bit more clear.

This may not be inconsistent with the documentation but it is 
inconsistent with good practice.  Wrappers should, in general,
set the default values, as the poster rightly indicated, and not the 
values themselves.  Its not a coincidence that multiple people 
have mentioned this.

The old header (which teasingly displayed some parameters and then 
ignored them) was clearly wrong, but the new one doesn't display the 
parameters.

This is pretty reasonable practice.  It's a wrapper that provides a 
subset of the functionality, but is guaranteed to produce a legal file 
of the type it claims to produce.  I don't see anything wrong with it.

2005-07-07 Thread Gabor Grothendieck
I just checked the svn.  I did not realize it had been changed that way
so you are right, its better and possibly marginally acceptable although
I do think it would be preferable to set the defaults rather than the
values though I would no longer argue as strongly.
