I have a text file like this 2.5 3.6 7.1 7.9 100 3 4 2 3 200 3.1 4 3 3 300 2.2 3.3 2 4 I used "r <- read.table("a.txt", header=T)" The row names becomes X2.5, X3.6... What I need is the row names are numeric, so I can use the row names as numbers on x-axis for plotting. e.g. "plot(colMeans(r)~names(r))",

Hi R Users, I have been trying to work out how to rename column names using grep, basically I have generated these column names using tapply: [1] "NAME" "X1.1" "X2.1" "X3.1" "X4.1" "X5.1" "X6.1" "X7.1" "X8.1" [10] "X1.2" "X2.2" "X3.2" "X4.2"

Dear all, I had to extracts/set elements from/in a matrix. Let say I have two vectors dim1 and dim2 of indices in the respective two dimensions of a matrix: I want to extract all the corresponding elements. I the case of a nxn matrix, dim1 <- 1:n and dim2 <- 1:n would extract the diagonal. I know one way would be to use the functions 'row' and 'col', but the matrixes I

Dear all, I may have overlooked something but the following piece of code causes me trouble: > a_data.frame(1:4) > a X1.4 1 1 2 2 3 3 4 4 > apply(a,2,cat) 1 2 3 4Error in ans[[1]] : subscript out of bounds > apply(a,1,cat) 1234NULL Is this the fact my data.frame has only one dimension ? (and do I forget somewhere (but where ?) to specify not to 'drop'

Ben Bolstad experienced something odd while running R CMD check over a package of ours using r-devel (yesterday's fresh). He tracked down the problem to a vignette calling 'library(MASS)'.

Dear R-users, I currently have trouble in trying to compile R-1.3.0-patched on Compaq OSF1. -------- >uname -a OSF1 adenine.fysik.dtu.dk V4.0 1229 alpha -------- The 'configure' step ended seemingly corretly: ----------------------- R is now configured for alphaev6-dec-osf4.0f Source directory: .

Dear R-users, I am currently facing what appears to be a strange thing (at least to my humble understanding). If I understood correctly, starting with the version 1.2.3, R memory allocation can be done dynamically, and there is no need to fiddle with the --nsize and --vsize parameter any longer... So far this everything seemed to go this way (I saw the size of my processes growing when I was

Hi, R-devel causes me still trouble. It dies with Error: couldn't find function "predict.loess" Execution halted for the package affy, but bash-2.04$ grep predict.loess ~/R-devel/src/library/modreg/R/*.R /misc/homes/laurent/R-devel/src/library/modreg/R/loess.R:predict.loess <- function(object, newdata = NULL, se = FALSE, ...) bash-2.04$ ..the function seems to be there...

Dear R-users, I successfully installed the package Rstreams under linux, but my first attempt to do so on SGI IRIX 6.5 (64bits) lead to the following error message. -------------------- laurent at genome> R CMD INSTALL Rstreams Installing source package `Rstreams' ... creating cache ./config.cache checking for ftruncate... yes checking size of long double... 16 updating cache

Dear All, Would anybody have any advice to give on that: The Facts: - I installed (compiled) R on SGI IRIX (6.5) - I am not root - I discovered the jpeg device I need now badly doesn't work (postscript is not so happy with 19 millions spots) - after investigation, it appeared the jpeglib.h was detected not recent enough at configure time - the jpeglib.h in /usr/include is version 6a - the

Dear all, I am looking for a way to read tiff data into R (this could be something the pixmap package users could find intersting). I could not find anything related but I suspect something to exists...somewhere... is it really the case ?

Hello Laurent, Ray and Greg, I tried the gmake settings. Yet, I still got an Error code 1 message when I run the test. running regression tests don't know how to make ../library/base/R/base (bu42). *** Error code 1 (bu21) Thanks you if you have any idea.

Dear all, I have recently experienced something with the function order I cannot explain: The help(order) (which I admit having overlooked before) rises even more my confusion... The following lines made me think order() was returning the 'order' each value in a vector would take when sorted. > a <- c(4.1, 3.2, 6.1) > order(a) [1] 2 1 3 Doing > plot(a,

Dear R-helpers, I have been trying to use the 'configure' feature offered to package writters... but could make it work. The matter may have been discussed before, and a rtfm answer with the place the answer is found is perfect (but I read the 'writing R extensions' manual). The problem is: In my C code I have code conditional to a defined macro. I used autoconf the naive way

Dear all, I updated ('almost' painlessly =) ) the XFree version of my suse distribution 7.1 (could not wait any longer as the screensaver was crashing everything with irregular periodicity)... I have now Xfree 4.1.0 running (with OpenGL 3D going through the Mesa library), and I downloaded MS truetype fonts (as suggested by Mr. Suse). R seems to work... except (so far) the output of the

Hi, I am trying to compile R for 64 bits on a mainframe running IBM AIX. Setting the environment variable OBJECT_MODE=64 leads to hanging while checking whether leap seconds are treated according to POSIX... Interestingly, it works fine when OBJECT_MODE=32... Any pointer would help me much... Thanks, L. -- -------------------------------------------------------------- currently at the

Dear all, I compiled R-1.6.2 for IBM-AIX (using the native compilers) and I am facing problems to instanciate (rather) large matrices. I have: > m <- matrix(0, 640*640, 102) Error: cannot allocate vector of size 326400 Kb I am not truly familiar with AIX, but this does not seem to be caused by kernel/user limitations: ulimit -Ha gives: core file

Dear all, In the writing of functions for a package have to deal with (very) large arrays and I was considering that having them in files rather than in memory would help me a bit on the memory side of the things. I was thinking of accessing the elements in the arrays by 'seek' and friends in C. The package RObjectTables seems to provide the framework to do this kind of thing, but I

Hi there, I am interested if there is anyway to keep track of the occurrence of warning message. I know that warnings will only be printed out at the end of the program if warn=0. However I am also interested at which particular set of data does the warnings occur too. This is because I am running 1000 data, so if there are 2 or 3 data that give warnings, I would like to know which are the ones

Dear everybody! I m seeking the package named hdarray for the analysis of microarrays data. It must not included in the base packages. Thanks in advance.
