[R] Multiple groupedData plots in a postscript file using a loop

[Karl Knoblick]

Hallo!

I want to plot multiple grouped data in a postscript
file using a loop. As I use a loop no plot (or just
one empty plot) is generated. Here an example:

library(nlme)
data(Loblolly) # example data from nlme
postscript("PSFile.ps")
for (i in 1:1) # just as example
{
	plot(Loblolly)
}
dev.off()

Result: Just an empty PSFile.ps.
(Withoput the loop it works.

May anybody help?

Karl
