Right, so I'm using ggplot2 in R to create a graph that involves transparencies (no way around it I'm afraid).

In Latex I use latex - dvips - ps2pdf to compile, because I also need psfrag (and pstricks) and as far as I'm aware, that is the only way to do it. So I need to export the graph from R in an .eps file, right?

So then I get to the problem of dev.copy2eps not supporting transparencies. But I can get around this using cairo_ps, which gets the transparencies to work, but unfortunately now psfrag no longer works...

Any ideas how to get around this?

Minimal example - plots in R:

df <- data.frame(xmin=c(0,0.5), xmax=c(1,1.5), ymin=c(0,0.5), ymax=c(1,1.5))

p <- ggplot() + 
  scale_x_continuous(name="x") + 
  scale_y_continuous(name="y") +
  geom_rect(data=df, mapping=aes(xmin=xmin, xmax=xmax, ymin=ymin, ymax=ymax), color="black", alpha=0.5)

cairo_ps(file='cairo.eps', width=5, height=5)

X11(width=5, height=5)

Minimal example - LaTex ( LaTex + dvips + ps2pdf + view pdf):



\psfrag{x}{X axis}
\psfrag{y}{Y axis}


And here's what I get:

transparency works on left, psfrag works on right

Edit: Christoph is right, it works correctly for me on two different Ubuntu machines. The problem occurs on a Windows 7, also with R 3.0.2 running. I guess migrating the topic to the LaTex forum wasn't such a good idea after all. Can it be moved back?

Cool, thanks Werner, and sorry for not doing that in the first place! – maja Feb 26 '14 at 22:51
For me it works with R version 3.0.2 on Debian: i.stack.imgur.com/DAbmG.png – Christoph Feb 27 '14 at 9:40
Thanks Christoph, edited and requested migration back! – maja Feb 27 '14 at 11:49
try the tikzDevice, it can be a pain to install, but once it works it's pretty sweet – baptiste Feb 27 '14 at 12:33
maja: Your original question is still there at StackOverflow, you need to (let it) reopen there. – Stefan Kottwitz Feb 28 '14 at 15:51
