Jean, It's definitely bigger now, but my axes are cut-off. As in your example, I had them drawn after generating the heatmap, but the image does not seem to be centered. I think even part of the heatmap is getting cut off, which wasn't happening until I explicitly set the width and height of the pdf. Here is my code
> pdf("Apo_Mut_Boot.pdf", width=200, height=200) > heatmap(x=as.matrix((Apo_Mut)), col = > colorRampPalette(c("white","black"))(256), > zlim=c(min(Apo_Mut),max(Apo_Mut)), add = FALSE, xaxs = "i", yaxs = > "i",xaxt= "n", yaxt = "n", xlab="residue", ylab="residue", > main="Apo-Mutant",revC=TRUE, Rowv = as.dendrogram(blah2), Colv = > as.dendrogram(blah2), reorderfun = function(d,w) rev(reorder(d,w)), > oldstyle = FALSE,cexRow=0.01,cexCol=0.01,symm=TRUE ) > axis(1, at=1:919, labels=RowCol, las=2, cex=0.01) > axis(4, at=1:919, labels=RowCol, las=2, cex=0.01) > box() > graphics.off() Jacob -- View this message in context: http://r.789695.n4.nabble.com/Reading-labels-for-very-large-heatmaps-tp4644739p4645391.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
