dear R graphics experts---if anyone is running the combination of R 2.7.0 and ghostscript (2.62), could you please run the following and let me know if you get the same strange symbol size that I do, or if there is something weird on my system? regards, /ivo pdf(file = "testhere.PDF", version="1.4", pointsize=14); plot(0, xlim=c(0,26), ylim=c(-1,4.5), type="n" ); text(10, -0.5, "line 1 is plain, line 2 should be the same, except blue\nline 3 should be 1.5 times the size of line 1, but otherwise the same\nline 4 should be like line 4 except blue.\n\nthis gets weird symbol sizes at certain spots after ps2pdf14 is applied\n --- R output or ps2pdf error?", cex=0.5); points(1:25,rep(1,25), pch=1:25); points(1:25,rep(2,25), pch=1:25, col="blue"); points(1:25,rep(3,25), pch=1:25, cex=1.5); points(1:25,rep(4,25), pch=1:25, col="blue", cex=1.5); text(1, 0.2, "1 != 2", srt=90, cex=0.5); text(16, 0.2, "1 != 2", srt=90, cex=0.5); text(19, 0.2, "3 != 4, 1 != 2", srt=90, cex=0.5); text(20, 0.2, "(1,2) > (3,4)", srt=90, cex=0.5); #text(20, 0.4, "shrunk on cex=1.5", srt=90); dev.off(); retcode= system( "ps2pdf14 testhere.PDF" ); # now look at testhere.PDF.pdf , which is the ps2pdf14 output ;

Problems with evince using an old poppler version (such as you get with Fedora 8) were reported recently, and seem to have been fixed with the newer version of poppler used in debian unstable. -- George N.

thanks. I am now using R-patched 2008-05-18 r45723 . This is
probably intended, but if not, I wanted to note it briefly: on the pdf
output device, symbol 1 is always black, no matter what color is
selected. symbols 10 and 13 contain black. symbol 19 is the
replacement for symbol 1 that takes on the color.
forgive the semicolons:
pdf.start("test"); # just encapsulates what you would expect.
NM=25;
plot( 0, type="n", ylim=c(0,6), xlim=c(0,NM), xlab="0-8",
ylab="0-5" );
points( 1:NM, rep(1,NM), pch=1:NM, col="black");
points( 1:NM, rep(2,NM), pch=1:NM, col="green");
text( 1:NM, rep(3,NM), 1:NM, col=1:NM, cex=0.75);
pdf.end();
