Here you will find a file (Bitmap, 769Kb) to reproduce the problem: http://www.statistik.uni-dortmund.de/leute/ligges/R/test1.bmp Using file.copy("c:/test1.bmp", "c:/test2.bmp", overwrite = TRUE) produces a second file with the size of ~1.4 Mb: http://www.statistik.uni-dortmund.de/leute/ligges/R/test2.bmp To reduce size, I put both files into following zip archive: http://www.statistik.u...

3d Map with bars
Apologies in advance for the question. I am trying to draw a map of the US as a surface plot so that I would be able to drop bars on the different states (something like Uwe Ligges' scatterplot3d example 4). I am not sure where to start looking for such a beast. If anyone has any pointers, ideas, I will be grateful. TIA, Partha

Strange behavior of savePlot
Hi all, I am using savePlot in a loop for saving several graph but I get some graph in 553x552, some other in 1920x1119. How comes ? My data are almost all the same (same label, same xlim / ylim, almost same data. Only the color changes). I save them in bmp. Thanks for your help. Christophe

It's weird! I am sure that I have inserted "browser()" in a sub-routine where I wanted to stop and debug... But when I start running the main function from the separate main file, it doesn't stop within the target sub-routine at all. Please help me! Thanks!
