The following is my code for heatmap.3:

heatmap.3(x = as.matrix(res), dist.FUN = dist2, scale = 'row', color.FUN = col_ylgnbu, cex.main = 2, trace = 'none', srtCol = 45, adjCol = c(1,0.1), main = paste(title), key = T, cexRow = 2, cexCol = 1)

I get the following heatmap using this code:

Is there a way to adjust the column labels so that they do not overlap the heatmap? This post has been cross-posted here but I thought I'd post it here too.

Thanks!

If you are talking about the heatmap.3() function from the GMD package, then you should direct your queries to R-help (r-help@r-project.org), as that is a CRAN package, not Bioconductor.
