Hello,
I've been using a pre-release version of R v 2.8.0 for Windows for the last
couple months. I think that there have been consistent problems with
subsetting data sets, but I had usually been able to find work-arounds or was
unable to confirm this as a bug. I think now I have, and would love advice on
what to do if I've made some error.
The data set in question ("c") has 500,000 observations and 44 variables. The
problematic variable, "month," takes integer values 1:12, and all are present in the data
set:
unique(c$month)
[1] 11 10 9 8 12 1 7 4 6 2 5 3
However, I can't select observations of c for certain values of month:
...
length(c$month[c$month==11])
[1] 0
Hmm.
Does any of these make us any wiser?
mode(c$month)
any(c$month==11)
table(c$month)
dput(unique(c$month))
