[Tikzdevice-bugs] Respecting ggplot2 element_text font family

[Alastair Andrew]

Hi,

Is there anyway to get RTikzDevice to use the same font face as you've 
specified in family argument of element_text?

For example:

library(ggplot2)
p <- ggplot(diamonds, aes(carat, ..density..)) + geom_histogram(binwidth = 
1)
p + facet_grid(. ~ cut) + theme(strip.text.x = element_text(family="mono"))

This example will have the facet labels typeset in a monospaced font. If I 
use the tikzDevice the output will just have normal serif font face. Is 
there anyway to achieve the look I want without manually wrapping the facet 
labels in a LaTeX \texttt{}. I tend to find that approach leads to unusual 
spacing issues. Especially in the legend. 

Thanks,
Alastair.
