Here's a strange bug. I recompiled R 1.2.0 in Windows with DEBUG=T, and this gives pretty() some pretty strange behaviour. If executed just after a session opens: > pretty(c(-0.015,1.015)) [1] -2.000000e-01 -2.775558e-17 2.000000e-01 4.000000e-01 6.000000e-01 [6] 8.000000e-01 1.000000e+00 1.200000e+00 The same result repeats if I repeat the command. However, if I now ask for help on pretty, close the help window and try again: > ?pretty > pretty(c(-0.015,1.015)) [1] -0.2 0.0 0.2 0.4 0.6 0.8 1.0 1.2 > This doesn't happen with the Windows binary distribution. The compiler I'm using is the mingw32 compiler, with version information gcc version 2.95.2 19991024 (release) Is this a compiler problem, a problem with DEBUG=T, or something wrong with pretty?
