[R] Perpendicular symbol in plotmath?

[Matthew Neilson]

Thanks for your response, Gabor.

That works quite nicely. The documentation states that it is not possible to mix and match Hershey fonts with plotmath symbols. My *ideal* scenario would be to write the 
perpendicular symbol as a subscript (specifically, I would like to have " \epsilon_{\perp} " as an axis label).

I have searched the help archive, and it turned up the following post from 2002:

which explains a way of "faking" subscripts when using the Hershey fonts, though it does have several drawbacks. Have things moved on in the last five years, or is this still the best 
known solution?

Many thanks for your help,


-Matt
