Hey,
Does anyone know of an equivalent to the LaTeX \perp (perpendicular)
symbol for adding to R plots? Parallel is easy enough ("||"), but I
haven't been
able to find a way of adding perpendicular. The plotmath documentation
doesn't mention how to do it, so I'm inclined to think that it
doesn't
exist - but surely there must be some way of achieving the desired
result,
right?
Any help will be much appreciated,
-Matt
Its available in the Hershey fonts:
plot(0, 0, type = "n")
text(0, 0, "A \\pp B", vfont = c("serif",
"plain"))

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:
http://tinyurl.com/2m8n9c
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
