Hi, I have a problem using heatmap.2 function of gplots library: heatmap.2(x=matrix(1:36,6,6)) Error in axis(1, 1:nc, labels = labCol, las = 2, line = -0.5, tick = 0, : X11 font at size 15 could not be loaded or heatmap.2(x=matrix(1:25,5,5)) Error in axis(1, 1:nc, labels = labCol, las = 2, line = -0.5, tick = 0, : X11 font at size 16 could not be loaded or heatmap.2(x=matrix(0,5,5)) Error in axis(1, 1:nc, labels = labCol, las = 2, line = -0.5, tick = 0, : X11 font at size 16 could not be loaded but not with matrices of other dimensions, bigger or smaller ones.. This happens on my R with gplots 2.3.2 and gdata 2.3.1 but not on the R of a colleague of mine, and he has gplots 2.3.1 and gdata 2.3.0 This is my full sessionInfo() R version 2.4.0 (2006-10-03) x86_64-unknown-linux-gnu locale: LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US .UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.
