[R] greek letters in "italic" font

[Luis Tercero]

Dear HelpeRs,

I am trying to write axis labels with some letters in cursive for later 
inclusion in a LaTeX document. The following code does what I want with 
latin letters (c cursive and the rest not cursive):

plot(1:10, 1:10, ylab = expression(italic(c)*(MB)))
or
plot(1:10, 1:10, ylab = expression(paste(italic(c)*(MB), "  /  ", 
mu*g~L^{-1}))

but it does not work for greek letters:
plot(1:10, 1:10, ylab = expression(italic(rho)*(MB)))

Using text() or mtext() with the option font = 3 does not work either.

I found a way around this by writing "rho" and then having "rho" be 
changed to the corresponding greek letter in LaTeX by using the PSfrag 
package... but it only works for text(), not for mtext() nor xlab/ylab 
within the plot() command.

I would be grateful for some ideas.

Many thanks and best regards,

Luis
