Hello, I'm trying to calculate a certain distance estimator for my thesis. I have a program in C that works fine when I call it with .C() in R, but since I'm dealing with big matrices like 30000x20000 it was getting a stack overflow. Now I have the same program but more efficeintly coded using malloc, and it works perfectlry in C, compiles well with R CMD SHLIB but when I call it with

Hi, dear all: I am a beginner. I appreciate any help or hint from you. I am trying to do calculation with matrices. I have 3 matrices. One is matrixA, 2nd is matrixB, and last is matrixC. Here is matrixA: 1.8511.40.0831.001 0.8771.30.1161.33 1.9021.21.1020.302 0.8640.1261.110.252 1.8230.2161.0020.307 Next is matrixB: 0.8761.770.1930.328 0.8911.0090.2381.004

Dear R Users, Is it possible to add another (third) index to matrix (as in MATLAB). For some analysis e.g. finite mixture models is necessary. Simple example i<-3 matrix[, , i]<-matrixA[, ,i]%*%matrixB[, , i] I would appreciate any help Rob

Hello, I am hoping for some advice on using R - my experience with statistical programs has been limited to SPSS. I have been using a textual analysis program and wanted to add some rigour to making a choice between two models of self-reported cannabis effects. To do this, I need to compare the two resulting word co-occurence matrices. The program itself,doesn't offer this as an option

Can someone please refer me to a function or method that resolves this structuring issue: I have two matrices with identical colnames (89), but varying number of observations: matrix A matrix B 217 x 89 16063 x 89 I want to creat one matrix C that has both matrices adjacent to one another, where matrix A is duplicated many times to

Hi everyone, after following in the footsteps of the following discussion (http://lists.xenproject.org/archives/html/xen-users/2013-09/msg00106.html) I had been able to turn my GTX 480 into a Quadro 6000. When I VT-d passthrough it to a Debian jessie VM it shows up fine and CUDA 5.5 seems to function properly up to a point: lspci -v: 00:04.0 VGA compatible controller: NVIDIA Corporation GF100GL

Hi List, Is there any way to pass on directly VBA variable content into a R variable? on windows XP & using R 2.12.0 I have installed RExcel addin (with associated D(COM)) >> It function fine when trying to pass Excel Range to R but I failed (sorry if it is only my own limitation, search till now unsuccessful) to find out how to pass directly VBA array into R Below an example -

Hi List, My apologies in advance if question is simplistic, I am quite new to R graphics capabilities and I could not find anything in past threads... I use R 2.8.1 under Mac OS X, but I would preferrably have a cross platform answer as I use also R under Windows I produce plots using R & save them in a file e.g. below: y <- rnorm(1000) x <- rnorm(1000) plot(x,y)

Hi, Being relatively new to OO programming and not so old on R, I noticed the possibility to do OO programming in R. But it seems there is two "paradigms" S3 that seems the old one but is the one used in the R.oo package and S4 which seems more recent As a starting point, which one is best to use? Is R.oo useful? what are the main difference between the two? Any feedback

hi, I have been attempting to run this script and am getting some strange results. The script connects to a database and retrieves a series of tables, using sequential sql statements. I have tested all of the sql statements in the PostGreSQL terminal and they all return the desired results. I place each table into a list and run a FOR loop for 'i' in the list. The script generates

Hi, I?d like to ask for some help in writing a loop. My situation is the following: I have a matrix (matrix.A) containing 3 columns and 100 rows. The columns represent parameter estimates a, b, and c. The rows contain different values for these parameter estimates. Each row is unique. I want to insert these parameter estimates into a model (say, y = a + bx + cx^2) and solve for y given a

Dear all, I know this topic has already been covered in other posts (at least the for loop Vs apply family of function), but I am looking for fresh / up-to-date opinion and feedback on those 3 methods to run unavoidable loops in R. I realise that it may be too general question for many, so any feedback appreciated. 1. apply Vs for loop >> Seems apply is (was?) supposed to be faster than

Dear list, I could not find a mailing list of R under ubuntu, so I give it a try here...any direction/suggestion welcome I run R 2.8.1 under Ubuntu 9.04 >From the terminal I am able to run a R CMD BATCH command when I am on my home folder /home/user jc@jc-laptop:~$ R CMD BATCH /var/www/test.R The file "test.R" contains simply: a <- 1 write.csv(a,"/var/www/test.csv")

Dear all, I have run into a problem when running some code implemented in the Bioconductor panp-package (applied to my own expression data), whereby gene expression values of known true negative probesets (x) are interpolated onto present/absent p-values (y) between 0 and 1 using the *approxfun - function*{stats}; when I have used R version 2.8, everything had worked fine, however, after updating

Dear list, I use the R CMD BATCH to run a file of R commands (from php for info) This file of R commands contains a line to source a configuration file "source('path/conf.R')" In this configuration file I define some variables, e.g. the path of some file (uploaded before this R CMD using php) "PathUpload <- 'path/uploads'" What I would like to

Hi guys, I need to insert a row to a matrix in a for loop. I have matrix named "Avg" which is a 5x4 matrix of zeros. I have a file named "A"(4 rows,14 columns) which I make a sample of it 5 times. each time I get the mean for each column and put the result in the "Avg" matrix. this is my code: Avg=matrix(0,5,4) > > for(i in 1:5){ + res=(A[sample(nrow(A),

Dear R users, I am new to Latex and I am using the R package xtable to generate tables. I want to produce a table that is very long. in the landscape format, but I would need to rescale the table so that it fits in the page. xtable enables me to have the landscape format, but I cannot rescale it, and there seems to be a problem, if I use scalebox in Latex on my output produced with stable and the
