Looking at the help page for heatmap it seems highly probable that it  
is a base graphics function since it uses layout, so ...

?par  #  very often the answer to plotting questions and is linked  
from the help page for heatmap, further evidence of my supposition.

The specific choices you need to make from there (with arguments font  
and family) are going to be determined by the specifics of the  
(unstated) device you are using.

?device
options("device")
