Hi BioC,

is there any function/parameter settings in R/BioC which adjusts the Heatmap image based on sample size and number of genes which needs to be plotted on image. 

The problem is when I generate Heatmap with :

bitmap(file = Hfile, type = "png16m", height = MapH, width = MapW, res = 72, units = "px",pointsize = 16);

where Hfile, MapH and MapW are variables I use to generate heatmap image file. (PNG)

if samples are 500 and genes are 300 .... it works with certain margin , height, width but if I do.. 500 samples and 4 genes only..the size are too big..I mean its obvious there are less num. of genes to plot..but is there any parameter settings which will adjust image size?

Thank you so much in advance,
