There's something (probably a lot) missing in my understanding of
plotmath. The LaTeX code for what I'm trying to produce is
\log(-\log(\hat R))
My (probably hopeless) attempt at it uses nested group()s:
expression(plain(log) * group("(", -plain(log)*group("(",
\hat(R), ")"),
")"))
Can anyone do it right for me, please?
Thanks,
Ted.

(If you are attempting anthing serious, the TeX package psfrag is worth a look.) -- Ross Ihaka Email: ihaka at stat.auckland.ac.nz Department of Statistics Phone: (64-9) 373-7599 x 85054 University of Auckland Fax: (64-9) 373-7018 Private Bag 92019, Auckland New Zealand
