Hello, I see this problem in 2.14.1, a recent dev, and 2.15.0 alpha, but not in an older build.
Start the R windows console and run this code: plot(1:10);windows();dev.off();points(10:1) The second set of points does not show up until the window is minimized and restored. If the device is replaced with a file-based one (pdf, png) there's no problem. I see this behaviour on these versions: R version 2.15.0 alpha (2012-03-13 r58726) Platform: x86_64-pc-mingw32/x64 (64-bit) R Under development (unstable) (2012-02-28 r58513) Platform: x86_64-pc-mingw32/x64 (64-bit) R version 2.14.1 (2011-12-22) Platform: x86_64-pc-mingw32/x64 (64-bit) I have an old beta install of 2.13.2 where the problem does not occur: R version 2.13.2 beta (2011-09-22 r57035) Platform: x86_64-pc-mingw32/x64 (64-bit) Cheers, Mike. -- Michael Sumner Institute for Marine and Antarctic Studies, University of Tasmania Hobart, Australia e-mail: mdsum...@gmail.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
