It would appear to me that there is a bug in the postscript device when multiple pages are required. Line widths can be only 1 after the first page. I have not seen reference to this as a problem before. test.device <- function() { # looks like the problem is in the postscript device postscript(file = paste("Test.ps"), horizontal = F) on.exit(dev.off()) par(mai = rep(1, 4), lwd = 12) for(j in 1:3) { plot(1:10, 11:20) title(paste("Testing .... Page", j), line = -1, cex = 1.5) } } The above code does not have a problem in Splus 3.4. It makes no difference in R if the lwd parameter is set in the plotting call itself. Has anyone a work around apart from doing separate plots for each page? platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 1 minor 1.0 year 2000 month June day 15 language R best -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188 ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~ I have the world's largest collection of seashells.
