I have tried this on my MacBook Air 2011 (1.6Ghz i5, 4Gb memory, 128Gb flash) and Mac OS X 10.7.1 Using R 2.13.1 of 2011-07-08. The problem occurs when running R 64 bit. The 32 bit R doesn't have the problem. Berend _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
