Hi, This is a silly little question, but I can't find the answer. I have a matrix of expression values e.g. expression. When I display either one column or one row it displays a list e.g. expression[1,] or expression[,1]. Is there a way to change this behaviour? When I constructed a test matrix, the matrix worked as desired i.e. > togo <- matrix(c(1,2,3,4),ncol=2, nrow=2) > togo[,1] [1] 1 2 Why is the behaviour different?

Hi Heidi This is one is reasonably easy, I hope. You need version 1.6-1 or higher on your Mac. You have it on your Linux machine, but not on your Mac. That may be because you are getting a binary version from a repository and that is not up to date with the releases from the Omegahat site. If you have the compilers installed on your Mac, the R command install.packages("XML", repos = "http://www.omegahat.org/R", type = "source") will get the latest version (1.6-3) and build it.

Hi Duncan, I ran the XML as you specified below, and got version 1.6-2, instead of 1.6-0 which is the CRAN version. When trying the run saveXML the error message persists though. I think it might be a problem with my R installation (R version 2.4.1 (2006-12-18) built from binary), since the function seems to work on another mac (built from source). Also, it worked on a PC, which has an XML version older than the 1.6-0. Haven't had any other problems with R on this mac though.

Yes I have already tried that, class(expression) is matrix. But class(expression[1,]) is list as is class(expression[,1]). Whereas the class of my simple constructed matrix when looking at a single row or column is numeric i.e. class(togo[,2]). Thanks for the suggestion anyway.
