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.

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 On 2013-02-26 05:25, Richard Hu [guest] wrote: > 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 > > -- output of sessionInfo(): > >> sessionInfo() > R version 2.15.1 (2012-06-22) > Platform: i386-pc-mingw32/i386 (32-bit) > > locale: > [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 > [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C > [5] LC_TIME=English_United States.1252 > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > other attached packages: > [1] Heatplus_2.4.0 > > loaded via a namespace (and not attached): > [1] tools_2.15.1 > > -- > Sent via the guest posting facility at bioconductor.org. -- Alexander Ploner Medical Epidemiology & Biostatistics Karolinsksa Institutet www.meb.ki.se
