I've tried:
plot(1:10,main=expression({sigma^2}[11]))
(and variants). Thi
Hi Rolf,
This is not addressing your implementation, but reformulates the goal.
Specifically, the covariance matrix is normally written as \Sigma (not
\sigma^2).
So to specify the upper left element you would write (in Latex)
\Sigma_{11}.
No superscript (so no problem!)
HTH,
Eric
