Hi everyone, >From the currently available version of the package VBmix, I would like to retrieve the intermediate .tex file that generates the VBmix-manual.pdf file. Formerly, running R CMD check with --no-clean allowed to get this tex source from a hidden directory : this feature was removed, but can apparently still be accessed through R CMD Rd2pdf --no-clean. Surprisingly, while the

Hello everyone, Considering the following code sample : ---- indexes <- function(vec) { vec <- which(vec==TRUE) return(vec) } mat <- matrix(FALSE, nrow=10, ncol=10) mat[1,3] <- mat[3,1] <- TRUE ---- Issuing apply(mat, 1, indexes) returns a 10-cell list, as expected. Now if I do: ---- mat[1,3] <- mat[3,1] <- FALSE apply(mat, 1, indexes) ---- I would expect a

Dear R contributors, I'm running into trouble when trying to allocate some large (but in theory viable) vector in the context of C code bound to R through .Call(). Here is some sample code summarizing the problem: SEXP test() { int size = 10000000; double largevec[size]; memset(largevec, 0, size*sizeof(double)); return(R_NilValue); } If size if small enough (up to 10^6), everything is

Hi everyone, I am using eigen() to extract the 2 major eigenpairs from a large real square symmetric matrix. The procedure is already rather efficient, but becomes somehow slow for real time needs with moderately large matrices (few thousand lines). The R implementation statically extracts all eigenvalues (and optionally associated eigenvectors). I heard about optimizations of the eigen

I have a stupid problem that is currently driving me crazy... Let us suppose that I want to draw a big red square in the middle of my current device (say X11) I tried the following code : pushViewport(viewport(xscale=c(0,1), yscale=c(0,1)), just=c("center", "center")) vp1 <- viewport(x=unit(0.5, "native"), y=unit(0.5, "native"), width=unit(0.4,

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; int info = 0; double mat[4] = {2.5, 0.4, 0.4, 1.7}; double id[4] = {1.0, 0.0, 0.0, 1.0}; double lmat[3]; F77_CALL(dpotrf)("L", &d, mat, &d, &info); lmat[0] = mat[0]; lmat[1]

With the following code : I would like to plot 4 points, and have the circle and diamond shapes filled with grey. What am I missing ?

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)

Hi, I am an unix admin trying to install samba 2.0.7 on a HP unix 10.20 system. After a long string of checking messages, at end there is an ERROR message which abort the configuration: checking configure summary ERROR: No locking available. Running Samba would be unsafe configure: error: summary failure. Aborting config I was wondering what caused it and how to get around it. This is

Hi! My boss asked me to be able to share some directories on a FreeBSD Samba server with users already created (and used) on a NT 4.0 PDC server. So I followed http://www.sugoi.org/bits/index.php?bit_id=10 I just replaced the Windows 2k part by adding the NetBIOS name of the machine to the NT PDC. When I did the smbpasswd trick it worked like charm: testsmb# smbpasswd -j CH-DOMAIN -r PDC

Hi, I feel that i'm having a small problem with my upsmon configuration (maybe even simply a permissions problem) since I upgrade today to 2.0.2 I have apcsmart set up and talk to my ups no problem (upsc get answer). I have upsd running no problem! But when I try to start upsmon, it's unable to talk to my upsd. Having try a few option I found that saying RUN_AS_USER=root makes my upsmon

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

Dear R users, I would like to call R from C++ and Rcpp class library already compiled are a big advantage !! I have already read the doc/PDF in the installed package 5.0 and all the posts in this forum It's possible to get the source code (RcppExample.cpp) whitout Rtools ?? (i'm not familiar whit Rtools) many thanks in advance Roberto Iacopetti win XP sp 2.2600 Dev-C++ 4.9.9.2 R

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.
