Hi everyone. How can I draw a big heatmaps?
png("foo.png",10000,10000)
heatmap(x)
dev.off()
where x is a big matrix, say 200*200.
The code above generates a small heatmap in the middle of the png file
and leaves big margins. I expect it to take up more space so that the
labels are not overlapping.
Without having looked in detail - I cannot even allocate enough space
for a 10000x10000 and you certainly do not want to produce some 300Mb
file, do you?
Anway, to proceed, decrease the size of the margins, see ?par.

Thanks in advance.
