Change title fontsize in heatmap.2 function?
19,082
heatmap.2
use this statement to print plot title:
title(main, cex.main = 1.5 * op[["cex.main"]])
So You should set cex.main
argument in par
list. For example:
par(cex.main=0.5) ## this will affect also legend title font size

I am using the
heatmap.2
package to make a heatmap:heatmap.2(as.matrix(FOOBAR.txt[rowSums (abs(FOOBAR.txt)) != 0,]), col=scaleyellowred, margins = c(10, 20), trace="none", xlab = "Comparisons", ylab ="gene", lhei = c(2, 8), scale=c("none"), symbreaks=T, cexRow=0.5, cexCol=.7, main="gene comparisons")
The output gives me a heatmap look like I want and looks good with the exception that the main title font is large. How do I decrease the font size of the title? I can't seem to figure it out. I can alter the font of the axis labels but not the title.
