Dear r-devel:
I noticed that optim's finite-element derivative approximations operate on
par/parscale for the gradient (as documented in help(optim)) but on par for
the Hessian. (The same goes for optimHess, which calls the same Hessian
code.) This seems odd, so I am wondering if it is intended.
On R 2.10.1 on OS X (10.6.2) using an X11() device,
plot(1:10, 1:10, main = expression(pi))
makes a not-equal symbol instead of a pi symbol.
Other Greek letters (including capital Pi) seem to work. On a quartz device
the pi symbol is displayed correctly.
I don't know if the issue is on the R si
are.

If these points are not mistaken and the appropriate person wants to

Thanks.
