The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

I have dowloaded the Source Code of R,and I want to know the process of chi-sqared test,but how can I found it? [[alternative HTML version deleted]]

I found it useful to have contour be able to do line widths ... hope that the guts haven't changed an enormous amount in the current development version ... the patches are relatively trivial, mostly going by analogy with lty and col (although in my ignorance it took me a while to figure out what UNPROTECT(2) was and why it should be changed to UNPROTECT(3) ... hope this is useful.

Hi, I was looking for a Windows-specific R function to focus the console window and couldn't find one. The motivation is that after loading the tcltk package, the "main" Tk window "." is presumably focused but then immediately withdrawn (hidden) so the RConsole loses its focus and you have to click on it to continue typing. Would there be any interest in including a

Hello everyone, Does anyone know how to implement the argument "unit" in R's plclust function ? I used to use Splus where this argument exists but it has not been implemented in R's plclust. The reason why I switched from Splus to R is that Ward's method is not implemented for S's hclust whereas it is implemented for R's hclust. What I would need is S's plclust

Using Sweave in the tools library (R version 1.8.0: sorry i havent upgraded), it seems i cant use if statements in R chunks that make graphs. i have this: <<fig=TRUE,echo=F>>= par(mfrow=c(1,1)) if(exists("x")) plot(x,x) else{ plot(1,1,type="n") text(1,1,"data not available.\n") } @ and I get this error: Error: chunk 6 Error in parse(file, n,

Does anyone have an example of calling primitive or internal functions from C code that they would share with me? I am having trouble trying to figure out how to construct the proper arguments to pass to "do_subset_dflt" Here is the prototype: SEXP do_subset_dflt(SEXP call, SEXP op, SEXP args, SEXP rho); The R_FunTab from "names.c" gives some additional information on the

Good afternoon, After cuting a hierarchical tree using cutree(), how to check correspondances between classes and branches? This is what we do: srndpchc <- hclust(dist(srndpc$x[1:1000,1:3]),method="ward") #creation of hierarchical tree plclust(srndpchc,hmin=20000) #visualisation srndpchc20000 = cutree(srndpchc,h=20000) #returns 4 classes table(srndpchc20000 ) srndclass20000 =

I am trying to get documentation about the random number generator used in "sample". The help for sample does not mention it. Can anyone point me in the right direction. Thanks [[alternative HTML version deleted]]

In the optim() function there is a syntax : res <- .Internal(optim(par, fn1, gr1, method, con, lower, Here how can I see the inside-codes of ".Internal" function ?

Hello, I'm working with the function optim() from stats package, and inside this function is called the function .Internal(optim(....)) and I want to get the code of this function which would help me to understand why the Nelder-Mead algorithm doesn't converge with my data. I'm working under Windows XP. Could you reply to this adress because I don't belong to the mailing list

Hi all. I began examining the R source code in the last few days, for a better understanding of its structure. I read the manuals and digged deeply (maybe not enough?) into the source code, but I couldn't totally understand how .Primitive() works. Its effects, if I understand well, are quite clear to me (calling the C compiled counterpart of a "primitive" function), but where is its

I know I should probably RTFM for this question, but could someone tell me if R supports the idea of "viewing source" on any particular function you want to use? If I want to "view source" on the rpois() function, for example, can I do somethink like: source(rpois) To see how the function is implemented?

plot.hclust: Setting up a window for a dendrogram assumes the first link is the shortest and the last is the longest. This is not always the case when the clustering was done with hclust, method="median" or method="centroid", and the dendrogram sometimes doesn't fit within the window. I propose the fix listed below. src/main/ --- plot.c Wed Sep 17 01:03:39 2003 +++

Hello! I have the following problem. I would like to plot the hclust object "hcd" (bellow, at the end of the mail) with ticks at seq(0.05,0.25,by=0.05). I tried using the code plot(hcd) and plot(hcd,axes=FALSE) axis(2,seq(0.05,0.25,by=0.05)) In both cases, the resoult is the same, ticks at 0.05 and 0.25 are not printed. I tried changing the ylim argumet in plot, however I got a

Ive created a postscript files that looks just like I want it to look except instead of being 6'' x 6'' i want it to be 2''x 2''. i used the postscipt() function (R 1.5.1 on redhat). if i use width and height in par to change the scale the figure looks terrible cause cex,mar,etc.. dont appear to change. before i start tinkering with the cex's and mar... is
