Hi all,

I noticed an undocumented feature for split. It sorts the resulting list 
according to the grouping factor. An example:

test <- data.frame(x=rnorm(48), f=letters[sample(1:8)])
split(test, test$f)

I wasn't expecting this behaviour, although I was pleasantly surprised. 
I suggest that the help page for split be amended to include this 
feature. I know it's a small thing, but someone else may also find it 
useful to know.
