I am using R-2-15-1 with latest version of RTools under Windows 7 on a 64bit machine. When trying to build a dll from a simple test program matm.f I get the following error: > R CMD SHLIB matm.f gfortran -O3 -mtune=core2 -c matm.f -o matm.o f951.exe: out of memory allocating 312 bytes make: *** [matm.o] Error 1 Can someone please help NJ ________________________________ E-pos vrywaringsklousule Hierdie e-pos mag vert...

...nto one picture so that in one cell in image picture are both values from mat[1,1] and mat2[1,1]. mat<-matrix(1:4, 2,2) mat2<-matrix(4:1,2,2) x <-1:2 y <-1:2 image(x, y, mat) image(x, y, mat2) The only way I found is to mix x or y for both matrices let say xm <- sort(c(x,x+.5)) matm <- cbind(mat[,1], mat2[,1], mat[,2], mat2[,2]) image(xm,y,t(matm)) which lacks of elegance and is rather complicated when considering matrix with more rows and columns. Looking forward to any hint. Regards Petr

Hello everyone, Peter (see my earlier post) recommended the following script for finding the means and standard deviations and putting them in table form. However, I would like the standard deviations under the means in brackets. Can anyone check this code to see how this can be adjusted? library(xtable) dataset1 = matrix( c(1,2,3,4, 5, 6 ), 2 , 3) dataset2 = matrix( c(4,3,5,10, 1, 0), 2, 3)
