Dear Folks--
All this seems to me to behave the way you expect, recognising that column b
is a factor:
> AA <- data.frame(a=3:4, b=c('x', 'y'))
> AA[1,]
a b
1 3 x
> as.numeric(AA[1,])
[1] 3 1
> AA[,2]
[1] x y
Levels: x y
> as.numeric(AA[,2])
[1] 1 2
> as.character(AA[,2])
[1] "x" "y"
But this seems to me to be wrong:
> as.character(AA[1,])
[1] "3" "1"
Shouldn't it be:
[1] "3" "x"
to be consistant with the normal pattern of coercing factors to character
values?
If it is a bug, is this the right place to post it?
sincerely, andrewH
