Dear R Community, I tried to generate heatmap for a matrix of 1500 columns by 106 rows using the following R script:> pheatmap(tf.vs.DE.1.removeAllZeroCol, fontsize=3,border_color=NA)and got the graph (as attached Fig 1) Since the column labels appear very crowded, I tried to increase the cellwidth to stretch the graph horizontally. The idea was to show the graph section by section, but with clear/readable column labels (not overlapped labels). So I typed:> pheatmap(tf.vs.DE.1.removeAllZeroCol, fontsize=3,cellwidth=3,cellheight=3,border_color=NA)However, this time I only got middle part of the original heatmap (as attached Fig 2) I wonder if there is way I could output the whole graph after such horizontal stretch. If not, how do I get the left end of the graph. Thank you very much for any inputs! Kind regards, Ace -------------- next part -------------- A non-text attachment was scrubbed...

Thank you so much for the reply! I thought the file would automatically adjust
accordingly. But I just checked and found pheatmap does has width as parameter!

Why not define a graphics device that is wider?
