Hi Lara, Hmm, I've never seen column names rotated in R (certainly you could in graphics, etc. and this should do it in that case: lapply(strsplit(colnames(x), ''), paste, collapse = "\n") ). You could transpose the matrix so the columns become the rows and then just have numbers (1:1600) as the columns? That's the best solution I've found when dealing with large correlation matrices. I also usually set options(digits = 2) or thereabouts (or use round() ). I'd be interested in seeing any other ideas people have also as this has been troublesome to me in the paste some too. As much as I hate to say it, I find it easier to view some of these things in Excel (you can just write the matrix to the clipboard and paste into Excel or probably open office (though I have not tried)) because it has easy scrolls bars and zooming.
