...n in http://r.789695.n4.nabble.com/allocMatrix-limits-td864864.html, following what I have seen in ?"Memory-limits" I checked that ulimit -v returns "unlimited". I guess I must miss something, like contiguity issues, or other. Does anyone have a clue for me? Thanks by advance, Pierrick

...] <- mat[3,1] <- FALSE apply(mat, 1, indexes) ---- I would expect a 10-cell list with integer(0) in each cell - instead I get integer(0), which wrecks my further process. Is there a simple way to get the result I expect (and the only consistent one, IMHO) ? Thanks by advance for your help, Pierrick Bruneau http://www.bruneau44.com [[alternative HTML version deleted]]

Hi Pierrick, You're storing largevec on the stack, which is probably causing a stack overflow. Allocate largvec on the heap with malloc or one of the R memory allocation routines instead and it should work fine.

This isn't the help list for LAPACK, but as far as I can tell, dppsv expects a symmetric matrix input compacted as triangular, not a Choleski decomposed one. So try assigning lmat before the call to dpotrf. -pd > On 20 Dec 2014, at 22:06 , Pierrick Bruneau <pbruneau at gmail.com> wrote: > > Dear R contributors, > > Considering the following sample C code, that illustrates two possible > uses of a Cholesky decomp for inverting a matrix, equally valid at > least in theory: > > SEXP test() { > > int d = 2;...

I've been reading this list for a few weeks now and I've given advice on questions that look challenging but I've deleted MANY questions like these: "How do I (easy question found in the documents)?" Though I don't count myself an expert, I've known enough experts to see that they _HATE_ it when you don't invest some time before asking a question. I too have

Could someone help me in finding what is wrong or in suggesting maybe another path to follow for my statistical analysis?

Dear All,   any thoughts on how I can do the following:   let us say we have:   a <-c(2,4,16,28,48) b <-c(10,4,2,0.4,0.03) d <-cbind(a,b)   what I would like to do is to extract values of column b in the matrix based on the corresponding values of column a. For example: I would like to extract all b values that have a corresponding a value that is less than 24 into a numeric vector, so

Good day. I create a data frame like this: > data <- data.frame(a=1:10,b=11:20,c=21:30) I can subset this data.frame by saying: > data[data$a>7,] and I get this result a b c 8 8 18 28 9 9 19 29 10 10 20 30 I understand I should get the same result by saying

Hi all. I would like to highlight overlapping regions of two densities and I could not find a way to do it. Here is the sample code: myd <- c(2,4,5, 4,3,2,2,3,3,3,2,3,3,4,2,4,3,3,3,2,2.5, 2, 3,3, 2.3, 3, 3, 2, 3) myd1 <- myd-2 plot(range(density(myd)$x, density(myd1)$x), range(density(myd)$y, density(myd1)$y), type = "n") lines(density(myd), col=1, lwd=4)
