Dear All,
I'm not sure if I understand the parameter stringsAsFactors correctly. I'm
trying to convert the string columns in aframe1 to factors. But it
seems stringsAsFactors=T in as.data.frame() doesn't do anything. Could
anybody let know what is the correct way to converting strings to factors?
> aframe1=data.frame(x=LETTERS[1:10], y=LETTERS[1:10], stringsAsFactors=F)
> aframe2=as.data.frame(aframe1, stringsAsFactors=T)
>
> str(aframe1)
'data.frame': 10 obs. of 2 variables:
$ x: chr "A" "B" "C" "D" ...
$ y: chr "A" "B" "C" "D" ...
> str(aframe2)
'data.frame': 10 obs. of 2 variables:
$ x: chr "A" "B" "C" "D" ...
$ y: chr "A" "B" "C" "D" ...

Thanks,
John
