If you have a computer you can do much better histograms.  But since you 
have chosen to do this, one way is to edit the underlying C code.  It's 
available in

https://svn.r-project.org/R/src/appl/stem.c

Another way is to save the plot into a file, and manually edit the file.

The best way is to produce the whole thing by hand, using pen and paper, 
while sitting on a tropical island without access to a computer.  I 
recommend Half Moon Caye,
