Hi.. I am running R version 2.3.1 on a Windows XP machine with the latest Miktex 2.5 installed. I get no errors from R when running the Sweave example, testfile <- system.file("Sweave", "Sweave-test-1.Rnw", package = "utils") However, when I tex the resulting .tex file (after installing a4.sty) I get the error below.

However, when I ran this, MiKTeX prompted me to install the ntgclass package, which I did. Everything ran smoothly after that. I''m using R-2.3.1 with MiKTeX 2.4 in WinXP Pro. HTH, --sundar

I''m using R-2.3.1 with MiKTeX 2.4 in WinXP Pro.But he is using MiKTeX 2.5: looks like a problem with MiKTeX, as the latex error is in the initial processing. -- Brian D.

Hi all, I am trying to generate a distribution for the mean euclidean distance between a group of n elements in a given surface (the elements are randomly picked). Fo doing so I''ve written the following code: sampling<- function(x,size) { x<- x[sample(1:nrow(x),size),] mat<- matrix(c(x$V6,x$V7,x$V8), ncol=3) mean.dist<- mean(dist(mat,"euclidean")) } x is the file where the data are stored size is the size of the group mat generates a simple matrix. V6, V7, and V8 are the 3D (x,y,z) coordinates of the group elements . mean.dist calculates the mean pairwise distance between the objects of the group. Everything works fine but I want to repeat this many times (e.g. 10000) and store the mean.dist values in a new variable so I can generate the distribution of mean pairwise distances of a group of size n in my surface. Is there any easy way to do this? I''d really appreciate all your comments.
