Dear Dr. Ploner:
It would be great to be able to rotate the xtick or ytick labels
to any angle in your Heatplus package, which is very convenient when
labels are long.
Thanks
Richard Hu

Dear Richard,
neither annHeatmap nor annHeatmap2, the two functions that generate
annotated heatmaps in Heatplus, support rotated axis labels. This is
simply because they use the underlying R base graphics routines
(specifically the ?axis function) which do not provide this
functionality.
Personally, if I run into very long row- or column labels that won't
fit
or overlap, I try one of the following:
1) shorten the labels: generally, shorter labels are more informative
anyway; ?abbreviate or ?substr usually do the trick
2) expand space for labels: the labels-argument allows you to set the
parameter nrow, which controls how much space is set aside for labels
(default: 3); see ?annHeatmap2 and Figures 8 and 9 in the vignette
annHeatmap.pdf
3) reduce the font size of the labels: this will generally do very
little on its own, but it may help in conjunction with 1 or2;
controlled
via parameter cex of the labels-argument, see ?annHeatmap2
Hope this helps,
alexander
