Hi,

I have a problem with my heat maps.

I have a matrix of 222x2 of GO categories. I am using the heatmap.2 package
to output an image. either a png or pdf.

My problem is that the labels on the x axis are to many ,so that I can't
read them.

I would like to make the single item size bigger (row size), so that I will
be able to differentiate between the single lables.

But I didn't find how to do it.

I tried to change the

par(mar = c(3, 3, 2, 5), oma = c(3,2,2,6))


and also to make the resolution and sizes of my image bigger

png("image.png",res=600,height=2600,width=2600)


But none of these parameters has change the size of the single rows I still
can't read my labels.

Is there a way of making the image bigger?

THX
Assa
