Multiple groupedData plots in a postscript file using a loop

Thanks, but it does NOT work using a loop (your
example without loop works):
trellis.device("postscript", file = "PSFile.ps")
for (i in 1:1)
{
plot(Loblolly)
}
dev.off()
Yep, sorry. You need to print() a lattice plot in this case:
trellis.device("postscript", file = "PSFile.ps")
for (i in 1:1)
{
print(plot(Loblolly))
}
dev.off()

Just an empty postscript file. Karl. --- Uwe Ligges <ligges at statistik.uni-dortmund.de> :>
Note that this is a lattice plot:
class(Loblolly)
[1] "nfnGroupedData" "nfGroupedData" "groupedData"
"data.frame"
Thus, the method plot.nfnGroupedData() producing a
lattice plot is
called by the generic plot().
So, you don't want to start postscript(), but
trellis.device("postscript", file = "PSFile.ps")
plot(Loblolly)
dev.off()
