Dear all, we have installed R in one of our computer labs. Running demo(grpahics) works, kindof, in that it produces all the usual plots without crashing, but the plots are incomplete: no color wheel, no pie chart, no boxplots, just some labelling, titles, and in rare cases, axes. We have tried this with both 1.7 and 1.6.2, with the same results. The computers are running Windows 2000, with somewhat elderly video cards (NVidia Vanta with 8 mb of video RAM), the monitor is set to 1024x768 and "true colors" (32 bit). Has anyone suggestions why this might be? What might be done? Thanks! alex Alexander.Ploner at mep.ki.se Phone: 46-8-524-82329 Fax : 46-8-314975 Medical Epidemiology & Biostatistics Karolinska Institutet, P.O. Box 281, SE-171 77 Stockholm
Windows: Graphics appear only partially

I've no real idea: I used to run R happily on a W2k laptop with only 2.5Mb of video memory (1024x768, 24bit). Looks like a graphics driver problem to me: can you try 24bit or failing that 16bit?

We tried everything down to 8bit and 800x600 resolution, with the same results. alex Alexander.Ploner at mep.ki.se Phone: 46-8-524-82329 Fax : 46-8-314975 Medical Epidemiology & Biostatistics Karolinska Institutet, P.O. Box 281, SE-171 77 Stockholm

... or even safest: try to switch to the standard VGA driver if your graphic
cards allows it (supporting maximum resolution of 800x600). This way, you
will know if it is the graphic driver that causes the trouble. Then, if
answer is yes, three possibilities:
1) Look at NVidia web site if they propose a more recent driver that perhaps
corrects these bugs,
2) Go to control panel -> display -> settings -> advanced -> troubleshoot,
and move the slider to the left (hardware acceleration: none). If it works,
try sliding a little bit to the right and recheck R graphs, etc... until you
find the best compromise between hardware accelaration level and correct
graph display in R,
3) Change the graphic card as a last solution if everything fails :-(
Best,

Last week, I asked the list about help because graphics were not displayed properly on Windows 2000 machines in our computer lab. Brain Ripley and Philippe Grosjean kindly offered support and advice; it turned out that Philippe's suggestion to install the latest drivers for the elderly video cards in the machines (NVidia Vanta with 8 mb of video RAM) solved the problem.
