Dear R developers: The following R program produces a pdf file that does not survive ghostscript distillation correctly. The undistilled version is at http://welch.econ.brown.edu/temp/try.PDF while the distilled version is at http://welch.econ.brown.edu/temp/try.pdf . When previewed, the points are wrong in the distilled .pdf version, but only in one of the two points invokations (huh?) . The program that generated the pdf files is
x= 1:10; y1= x; y2= y1/2; plot.one = function( x, y ) { lines( x, y, col="blue"); points( x, y, col="blue", pch=21, cex=1); } pdf(file = "try.PDF") plot(0, type="n", xlim=c(1,10), ylim=c(1,10)) plot.one( x, y1 ) plot.one( x, y2) dev.off() system("ps2pdf14 try.PDF try.pdf") # distillation. ----------------------------- Obviously, the error can be in ghostscript, not in R. Or it can be that R produces a pdf file that has some slight problems that do not usually show up, except when distilled. Before I get too badly flamed, feel free to ignore this. I am just trying to help. It took me some time to whittle down the program to isolate the problem. R was invoked under OSX via "R --vanilla" and is version 2.8.1. ghostscript is 8.62 (2008-02-29) under OSX. (It should be easy to check whether this also occurs under linux.) /iaw ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
