Is there a way to adjust the borders of the heatmap output by the
sigGeneSet function in the gage package? When I run my data (3 treated
samples against 3 controls) using kegg.gs, I get very few significant hits,
so when the heatmap file is generated, most of both the sample names (along
the bottom) and the KEGG pathway names (along the right side) are clipped
off... Is there some way to effectively "zoom out" so that more of the
annotations are visible?

Thanks,
Alan
