Hello list, I am having trouble with "match" and "which" giving a NA result for some values, but not others. Here is a simple example:
> aaa <- seq(0,1,by=0.05) > aaa [1] 0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 0.50 0.55 0.60 0.65 0.70 [16] 0.75 0.80 0.85 0.90 0.95 1.00 > match(0.5,aaa) [1] 11 > match(0.6,aaa) [1] NA > which(aaa==0.5) [1] 11 > which(aaa==0.6) integer(0) > sessionInfo() R version 2.12.2 (2011-02-25) Platform: i386-pc-mingw32/i386 (32-bit) Am I missing something? Any thoughts?
