Full_Name: Zdenek Valenta Version: 1.9.0. OS: Windows XP Submission from: (NULL) (147.231.7.250) I could not copy/save (Trelis) graphics using R version 1.9.0. The graphics displayed normally, but copying/saving it only produced an empty file. Everything works o.k. with R rel. 1.8.1. Best regards, Zdenek Valenta

...is no sine curve. (this is on a fast dual processor linux machine with 2Gb RAM.) This is clearly a postscript problem, rather than a R problem, since reducing the length of t down to something like 2000 solves the problem. By looking at the file o.ps it looks like the line is drawn by one "rlineto" call per point, followed eventually by a "stroke" after the last point. I'm guessing that the postscript interpreter simply cannot remember so many points in the path before it gets to the stroke. The example above is artificial, but this problem appeared with a real data set t...

Filing as bug report. (An old version of Splus had a similar bug: If you want to use rlineto, you need to round *before* differencing.) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

Full_Name: Stephen Harker Version: 1.80 OS: linux (Yellow Dog 3.0 on ppc) Submission from: (NULL) (130.194.13.101) In creating a postscript file from a set of data in which the points are plotted using `points()' and lines drawn using `lines()' I have found since upgrading from R version 1.4? to 1.8 that the two sets do not coinicide completely. This is best illustrated by a simple
