puzzled with plotmath for matrix indices

Gerrit,

thanks & viele Gr??e nach Oberhessen :-)

plot (1, 1, ylab = expression (Z[list(i,i)]))

though that cannot be evaluated, either (due to [ not knowing what to do
with an index list)

for future searches: probably the easiest cheat is, of course,
plot (1, 1, ylab = expression (Z["i, i"]))

Anyways, I put the "how to" into the R Wiki page on plotmath.

And I suggest that it should be mentioned in the plotmath help => email
to r-devel.
