Subject: [Rd] Assigning into a dataframe (PR#734)
Message-ID: <200011101600.RAA03890@pubhealth.ku.dk>

I am not sure whether this is a bug or a feature, but I thought
that these two would have identical effects ...

> data(iris)
> iris[, 5] <- as.character(iris[, 5])
> is.factor(iris[, 5])
[1] TRUE
> is.factor(iris$Species)
[1] TRUE
> data(iris)
> iris$Species <- as.character(iris$Species)
> is.factor(iris[, 5])
[1] FALSE
> is.factor(iris$Species)
[1] FALSE

Cheers, Jonathan.
