similar to: An example (was RE: file connection, while, readLines and bro wser)

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

Hi Rob, [BTW, sorry about the crosspost

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

I am attempting to iterate over a file, processing it line by line. In my function below, I am only getting the first item over and over and over again from my test file rather than subsequent lines. How can I modify this to read lines sequentially? == iteratefile <- function(file) { f.con <- file(file) on.exit(close(f.con)) while( length(readln <- readLines(f.con, 1)) > 0 ) {

I realize this isn't quite the correct forum (but then I don't think that there is one). Anyways, I've just been given enough money to hire two programmer for at least two years to work on the following project: (for experienced programmers only, please, salary in the 70k range) BRIEF DESCRIPTION FOR JOB POSTING To develop a system for the manipulation and analysis of microarray

Byron Ellis has been making some progress on a hdf5 library for microarray data (and any other thing you want to put in there). In doing so some issues have arisen that are of more general interest. 1) hdf5 supports annotation (through comments) so it would be nice if the comment function in R became generic. I think this is backward compatible and basically not really an issue of any

Hi Everyone, I'm wondering if anyone here write AGI's in compiled binaries. I'm writing a small Cepstral AGI in Freepascal/Lazarus. I know there are some other AGI's out there, but I wanted to add some more functionality than what is available such as having the AGI determine if the "data" argument is plain text or a path to a text file and act accordingly. The

Hi. Robert Gentleman's solution works. Thanks. This seems to be a documentation bug; I will submit a separate report to the bug list for completeness.

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
