similar to: splitstr problem solved

Hi, all. Using the patched version of R-0.99.0, I cannot reproduce the following example from the strsplit documentation: (Example) unlist(strsplit("a.b.c", ".")) ## [1] "" "" "" "" "" ## Note that `split' is a regexp! ## If you really want to split on `.', use unlist(strsplit("a.b.c", "\."))

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] ==

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?

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

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

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 :(

Hello, I have a decent working version of that report writing library which I'm calling R Report Generator. For those who don't know, this is a small library I've been working on which lets you output just about anything to an HTML "report" while you work, or as the result of a script. I'm eventually going to have it do nifty things like produce DocBook XML. I have

Thanks to John Fox, Brian Ripley, and Peter Dalgaard for responding. The short answer (as in Peter Dalgaard's reply, already posted to the list) is that the models I'm concerned with can in fact be compared using ancova. The key fact is that while the parameters may not be nested, the subspaces I'm examining are. An additional note from Prof. Ripley on AIC and BIC (which I quote in

Hello, all. I've got what is probably a simple question about comparison of models using anova, specifically about the situations in which it's valid. I understand, I think, what's going on when the models are strictly nested (as most are in the demo(lm) examples). My question involves what happens when the models aren't strictly nested. In my particular case, I'm doing
