Dear R experts: this is probably correct behavior, but I do want to
point out that it is unexpected to someone not too well versed:
> test=factor("A","B","C","A")
> ifelse(test=="A", as.factor("A"), test)
[1] 1 2 3 1
ok, my factor was just coerced into integers, even though I have a
logical vector as my condition and factors as my true and false
values. this means that
> test[1:3]=ifelse(test[1:3]=="A", rep(as.factor("A"),3), test[1:3])
won't work. I do know how to program around this, but since it
stumped me for a while (in a more complex program, of course), I
thought I would drop this note.
regards,
