. If you go to Control Panel, Display, Settings, Advanced, Troubleshoot, and reduce the hardware acceleration, it may fix the problem. (Maybe it is worth adding this trick to the R for Windows FAQ?) -- Graham Jones, author of SharpEye Music Reader http://www.visiv.co.uk 21e Balnakeil, Durness, Lairg

[R] Name conflicts when passing arguments for one function to another
