[R] ASCII character set and hyphen

[Roland Kaiser]

Hi all!

I want to print a hyphen to a pdf() or postscript() device.
As the documentaion of postscript says
ASCII Character 45("-") is mapped to a minus sign (ASCII Character  
95) by default.
The advice given is to use "\173" for a hyphen.

But, the following code produces a curly brace
instead of a hyphen.

Thanks for any advice?

Roland

library(rgr)
pdf("foo.pdf", encoding = "ISOLatin1")
display.ascii.d()
mtext("\173", side = 3)
dev.off()
