resize and adjust the heatmap in heatmap.2

Question

I\'ve generated a heatmap like this:

The X-axis and Y-axis labels don\'t show

Answer 1

A few tips:

• to reduce the font size, use the cexRow and cexCol arguments, e.g.

  heatmap.2(x, ...., cexRow=0.5)
  

• Adjust the values in the hlei and margins arguments.

Answer 2

I see that you are already using the margins parameter, what if you just modify the arguments as @csgillespie suggested?

e.g., margins = c(8, 8)

Maybe also modifying the general plot margins before calling the heatmap() function could help

e.g., par(mar=c(10,4,4,2))

or for the outer margin

par(oma=c(10,4,4,2))

where par(mar=c(bottom,left,top,right))
