Dear R-Users,
I have the following problem: I would like to create a postscript file
containing an r-plot with the string "\\vartheta" in it (reason: this
is later converted to the TeX-string "\vartheta" and a vartheta is
printed in the figure). In the minimal example below, the problem is
that the created postscript file does _not_ contain the string "\\vartheta
" as a whole, but rather the following code:
...
284.38 36.00 (\\v) 0 ta
-0.300 (ar) tb
0.480 (theta) tb gr
...
The problem is, that the program which converts the created .ps file
to a .tex file does not understand this disrupted string. Why does the
dev.copy(postscript,..)-command produce such an output and how can I
prevent it from doing so? If I use a different string such as "\\v_i",
then everything works fine and "\\v_i" appears as a whole string in
the postscript file. So why does it not work for "\\vartheta"?
Thanks in advance,
Marius

remove(list=objects())
library(lattice)
x=c(1,2,3)
y=c(1,4,9)
xyplot(y~x,xlab=list("\\vartheta"))
dev.copy(postscript,color=F,horizontal=F,onefile=F,file="myfile.ps")
dev.off()
