Point him to William S. Cleveland’s excellent book /The Elements of Graphing
Data/, where Cleveland strongly recommends that tick marks should point
*outwards* ‘because ticks that point inward can obscure data’. See the
discussion on pages 31–35, and especially figure 2.12 and 2.13.

I find that

library(Hmisc)
setps("filename") # Or setpdf. You might also want to add 'color=TRUE'.
... plotting commands ...
dev.off()

usually gives much better-looking plots, and with thicker lines.
