Doh! I totally missed that, and was having PDF problems for other
reasons. And thanks for the self-contained example (slightly extended
by me):
pdf.reader -> "xpdf"
pdf(file='fooout.pdf')
hist(x <- rnorm(100))
y <- sin(x)
print(str(y))
cat(y,file='fooout.txt')
plot(x,y)
dev.off()
system(paste(pdf.reader, 'fooout.pdf'))
system('cat fooout.txt')
thanks again, Tom Roche <tom_ro...@pobox.com>
