similar to: [R] RE: too many arguments in foreign function call

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] ==

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 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

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?

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

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

Is there an implementation of a reasonable k-nearest neighbor finder already in one of the packages? -- +---------------------------------------------------------------------------+ | Robert Gentleman phone : (617) 632-5250 | | Associate Professor fax: (617) 632-2444 | | Department of Biostatistics office: not yet

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 :(

Here is part 1 of my long saga towards a more flexible modeling paradigm. Comments and hints are especially welcome. The simple version: Starting with a formula and data R goes through 3 main steps to get the data into a form suitable for fitting. 1) application of terms 2) application of model.frame (subset and na.action occur in 2). 3) application of model.matrix To be concrete

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

I've recently setup a distributed/replicated cluster and have had an issue with seeing the directories on the cluster. Also, a df -h only shows data from one of the three bricks. The strange behavior doesn't end there. If I log into the 'primary' server as root, then do an ls on the client, the directories appear. However, df -h is still incorrect. I'm not sure exactly

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.

I have a, no doubt, simple question. I wish to write a function such that a <- 9 b <- 10 changer _ function(x,y) { if (y>x){ x <<- Y+1}} Of course there are easier ways to accomplish the task above, but I am more interested in how to have the "x <<- Y+1" part of the function to change x in place for purposes of a much larger function. I have been wrestling with
