[R] problem formatting and positioning title in heatmap

[Mark W Kimpel]

I am using heatmap with the arguments below. The title size stays the 
same no matter what I set cex.main to. Is this expected? Can I adjust 
the title size in heatmap?

Also, the position of the main title is at the very upper edge of the 
output and if I use a "\n" to stack the title the upper line is out of 
bounds and doesn't show up.

I am outputting to pdf.

Any help? Thanks, Mark

heatmap(x = dataM, RowSideColors = RowSideColors, 
ColSideColors=ColSideColors, main = title,
           margins = c(50,50), scale= do.scale ,labRow=geneNames, 
labCol=colLabels, col = hmcol, cex.main = 1,
           cexRow = row.lab.mag, cexCol = col.lab.mag)
