Hi all
I wish to create a ps file of a picture produced in R.
With my limited R, I see two ways:
1. Print direct to the postscript device
2. Print to the screen, and save to ps using dev.print.
I want a white (not transparent) background. Option
1 above works fine, but 2 does not: even when I say I
want a white background, I get transparent; perhaps I
misread the help files.
Here's some R code:
### Method 1
### - print straight to postscript device
postscript(horizontal=FALSE,
onefile=FALSE,
bg="white",
width=4,
height=4,
paper="special",
file="testfile.eps" )
curve( dnorm, from=-3, to=3)
dev.off()
### Method 2
### - print to screen, and save using postscript
x11(width=4, height=4)
curve( dnorm, from=-3, to=3)
dev.print( postscript,
horizontal=FALSE,
onefile=FALSE,
bg="white",
width=4,
height=4,
paper="special",
file="testfile2.eps" )
I then want to place these files in a LaTeX prosper document
for a presentation. A typical (minimal) prosper file is:
\documentclass[pdf,colorBG,slideColor,whitecross]{prosper}
\begin{document}
\begin{slide}{Print to \textsc{ps} direct}
\includegraphics{testfile.eps}
\end{slide}
\begin{slide}{Print to screen first}
\includegraphics{testfile2.eps}
\end{slide}
\end{document}
The whitecross class provides a blue background for the
presentation. testfile.eps appears with a white background
on the slides, but testfile2.eps has a transparent
background.
I'd apprecaite if someone could explain why the two are not equivalent,
or how I can coerce the second option to have a white background? Or
even explain my misunderstandings (assuming (with high probability)
that I have some).
Thanks.
