[BioC] image size - How to make bigger images

[Heidi Dvinge]

Hi Assa,

from your post it's not completely clear to me whether it's the figure
itself that's too small, or the writing in the row labels. If it's the
latter, then have a look at the cexRow parameter in heatmap.2 for
increasing the font size.
