Hello, I am writing this message because of an incorrect output by paste(). Please try the following script to see if the evidence I collected is reproducible: x <- c(10152, 28177); y <- c(9576, 26625); d <- y - x; d; [1] -576 -1552 paste(d, collapse = ", "); [1] "-576, -1552" x <- x / 1000; y <- y / 1000; d <- y - x; d; [1] -0.576 -1.552 paste(d,

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

Hello, I am trying to compile R-2.9.1 on Mac OS-X 10.4 using --enable-R-shlib. I am not comfortable with Mac/Linux environments and trying to follow the instructions from CRAN site to every detail. The Mac OS did not have a gcc (gcc -version did not work). So I did the following: ## For gcc 4.2 and Fortran 4.2.4 Compilers Download gcc-4.2-5566-darwin8-all.tar.gz from

In the "filled bands" part of xYplot of the Hmisc package, is there a way to have multiple bands with multiple lines? or does it just allow one for now? So I had an example bit ago had a made up line and CI, now if I wanted to make a second line with a CI filled in can I put them on the same plot? x<-seq(1,10,1) y<-seq(1,10,1) ci<-y*.10 ciupper<-y+ci

Hello there I'm trying to compile llvm-gcc, but the compilation fails. This is due to the fact that the ConstantArray class does no longer have the getAsString method. It has been actually removed on Jan 31 (commit 6a89228faca4b30c4abc29b5dec98bdac011ea4c). Is there a patch for llvm-gcc which overcomes this problem? I've just svn-updated my working copy but it didn't change

The example here puzzles me. It seems like the < operator doesn't work as expected. > l <- 0.6 > u <- seq(0.4, 0.7, 0.1) > u [1] 0.4 0.5 0.6 0.7 > mygrid <- expand.grid("l" = l, "u" = u) > mygrid l u 1 0.6 0.4 2 0.6 0.5 3 0.6 0.6 4 0.6 0.7 > mygridcollapsed <- mygrid[mygrid$l < mygrid$u, ] > mygridcollapsed l u 3 0.6 0.6 4

"An Introduction to R" says that arithmetic operators coerce logical vectors to numeric vectors. This doesn't seem to be true for unary "-" however: > x <- 1:10 > p1 <- (x > 5) > p2 <- (-p1) > is.logical(p2) [1] TRUE > is.numeric(p2) [1] FALSE Since "==" always does binary comparison, this can lead to some bizarre behavior: > p1

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.

Hi everyone! I recently subscribed your mailing list, as I find the LLVM project interesting. I've read the document known as "Compiler hacker's introduction to LLV"[1], and I've learnt about LLVM-IR. I was wondering about the impact of such a representation on mixing code from different languages. Suppose we have a huge library X written in language LX, which we would be

Hi there, I am a bioinformatician working in DFCI. I am new to R. Yesterday I installed the R-1.7.1 to my Linux (since I am not able to find R-1.8 on the webpage). But I have some package installation problems ... 1. install.packages2() function isn't available. If I type at R prompt: >install.packages2("Biobase") Error: couldn't find function

Dear R People: I am getting some odd results when using logical operators: > x <- seq(from=-1,to=1,by=0.1) > > x [1] -1.0 -0.9 -0.8 -0.7 -0.6 -0.5 -0.4 -0.3 -0.2 -0.1 0.0 0.1 0.2 0.3 0.4 [16] 0.5 0.6 0.7 0.8 0.9 1.0 > x == -1 [1] TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE [13] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE > x

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 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

Hi All- This seems like such a pathetic problem to be posting about, but I have no idea why this testcase does not work. I have tried this using R 2.4.1, 2.4.0, 2.3.0, and 2.0.0 on several different computers (Mac OS 10.4.8, Windows XP, Linux). Below the signature, you will find my test case R code. My point in this folly is to take a dataframe of 300,000 rows, create a filter based on two

Hello! I don't know if there is some R-package able to associate ontology to a long list of GeneBank Name (a txt-tab file or an XML file), i.e. I would as output a formatted file with 4 columns (1:GeneBank Name 2,3,4:ontology). I know that I have to perform a mapping of genes, I got a look on AnnBuilder pkg, but I 've not idea from where to start. Some suggestion? Thanks in advance!
