R devel - Dec 1999 - plot() after split.screen() on postscript() Device produces inconsistent PostScript file (PR#378)

Full_Name: Boris Leykekhman
Version: 0.90.0
OS: Red Hat Linux 6.1
Submission from: (NULL) (131.136.242.1)


Problem:
Plot()  after split.screen() on postscript() Device produces PostScript file,
which crashes PS interpretter with error message: 
“Error: /undefined in fg”
To reproduce:
#----- Start R code
postscript("test.ps")
split.screen(c(2,2))
screen(1)
plot(c(1,2,3,4))
dev.off()
#----- End R code
Workaround:
Inserting the line with definition of  “fg”, taken from the correct PS file,
solved my problem.
The line is: 
“/fg {0.0000 0.0000 0.0000} def fg rgb”
It was inserted after:
“%%EndProlog2”
