[BioC] heatmap - changing title size

[Lina Hultin-Rosenberg]

Hi Marcus and Natalie!

Thanks for your reply! I tried that before I send out the mail but for some
reason it didn't work, I got an error message saying that the plot could not
be found. Now when I tried it again it worked fine!!

Problem solved, thanks again!

Regards,
Lina

Hello.

I think if you set the par(cex.main=.8) prior to the heatmap call, the size
of the title should change to the value selected in the par command.

Subject: [BioC] heatmap - changing title size

Hi all!

I am using the heatmap method to generate a heatmap of gene expression
values but I am having problems with some graphical parameters. I would like
to change the size of the title since now it is too large to fit into the
plotting area. I tried to change cex.main from within the heatmap call but
nothing happened and I also tried to change the size by calling par after
the heatmap call but that didn't work either. Probably there is an easy
solution to this but I can't really figure it out.

I would really appreciate some help!

Best regards,
Lina Hultin Rosenberg

Part of the code generating the heatmap
=========================================================================
jpeg(filename=file.name,width=1000,height=600);
heatmap(t(exprs(eset.filtered)),scale="column",labRow=samplenames.short,main
=string.main.hc,col=greenred(80),cex.main=0.8);
#par(cex.main=0.8);
dev.off();
