Just thought I would mention that there is a new O'Reilly book out, "Developing Bioinformatics Computer Skills", which is ok, pretty superficial about some things but at least it lets you know what is happening and where. R gets a few pages in there, 394-396, mostly nice press and accurate except that Bill Venables (hi Bill) may be surprised to find out that he is a member of the

Dear R-help, I think I have kinda isolated the problem I had to the following: i <- 0 while( {i <- i + 1} < 5) { if(i < 3) next print(i) } This seems to go into an infinite loop. After I break the execution, i has the value 1. At the R prompt, if I start from i <- 0 and keep typing {i <- i + 1} < 5, it eventually evaluate to TRUE. So why does the while loop not work?

The following appears to be a bug in 0.90 > x<-sample(10,1:4,rep=T) > x [1] 8 > ?sample > x<-sample(10,1:4,rep=T) > x [1] 5 Of course, I forgot the syntax but I still don't like the result. -- +-------------------------------------------------------------------------+ | Robert Gentleman voice: (617) 632-5045 | | Senior Lecturer

Prof. Tierney, Thanks very much for the info. Why does the loop work if I move the assignment out of the condition? E.g., the following works: i <- 0 while(i < 5) { i <- i + 1 if(i < 3) next print(i) } Regards, Andy > -----Original Message----- > From: Luke Tierney [mailto:luke at nokomis.stat.umn.edu] > Sent: Tuesday, October 02, 2001 3:36 PM > To: Liaw, Andy

Hi Rob, [BTW, sorry about the crosspost

Prof. Gentleman (and R-help), Here's an example of what didn't work. I still don't understand why. Function: trycon <- function(file, n) { f.con <- file(file, open="rt") on.exit(close(f.con)) i <- 0 while( length(readln <- readLines(f.con, 1)) > 0 ) { x <- unlist(strsplit(readln, " ")) if(length(x) <= 6 && x[3] ==

The Design library has been fully ported to R except for Cox proportional hazards regression modeling (using Therneau's survival package) which will be available in about two weeks. It will take much longer to make all the example code executable, is it currently contains many examples for which data are not provided. Thanks to Xiao Gang Fan <xiao.gang.fan1 at libertysurf.fr> who

(On Unix/Linux) Is it possible to set the --no-save command line option as an option in the .Rprofile file. I have looked in the sources and do not see any obvious (user initiated) ways of changing the command line defaults, but I am hoping I have missed something. I *know* I can write my own shell script wrapper that calls R with whatever arguments I want (and I do that). However there

It was my fault, as you have seen. Y matrix must contain successes and failures, and not successes and trials. Sorry for my ignorance and thanks a lot for your help.

A change to diag() between 0.65.0 and 0.65.1 which seems undocumented in the logs (apparently revision 1.3.2.1, `diag names') introduced if (is.array(x)) stop("first argument is array, but not matrix.") which has broken the code in rpart. This looks wrong to me, as diag used to cope happily with a single-dimensional array. Such things occur quite often as the output

My mistake :( Seems that there's another R installed by root. So when I use .libPaths() there're two of them: > .libPaths() [1] "/disk/hopper/projects/class/cse514/R/library" [2] "/usr/lib/R/library" How could the second path be enabled then? The R_LIBS have already been set to as the [1] only. Thanks, yan On Mon, 3 Mar 2003, Robert Gentleman wrote: > You

Yeah!! I finally get SJava examples run on linux. The problems is that there's an old version installed on the machine, with static library. Unfortunately, the path of the old version is set before the new version, thus every time when R command is conducted, the old version is invoked (but I didn't know), and since the libR.so is not exist in that version, I always got linkage errors :(

Hi, The help for `assign' says In all the assignment operator expressions, `x' can be a name or an expression defining a part of an object to be replaced (e.g., `z[[1]]'). The name does not need to be quoted, though it can be. So I would expect that by a<-1:4 assign("a[1]",2) the first component of a gets the value 2, but the object "a[1]" is

AARRGGHH! Sometimes it's the simple things that are particularly frustrating, especially late at night.... Can anyone suggest a simple means for replacing all of the zero values in a matrix with NANs? I ended up writing an awk script to massage the input file, which works, of course, but is rather an inelegant blunt instrument. I'd prefer an R operation. I'm certain that
