[R] as.logical(factor) behaviour

[Philippe Grosjean]

Hello,

According to ?as.logical:

"as.logical attempts to coerce its argument to be of logical type. For 
factors, this uses the levels (labels)."

However,

 > as.logical(factor(c("FALSE", "TRUE")))
[1] TRUE TRUE

Shouldn't it be the same as:

 > as.logical(levels(factor(c("FALSE", "TRUE"))))
[1] FALSE  TRUE

according to the documentation? Did I miss something here?

Thanks,
