Dear R People:
This is probably a very simple question. I know that if I want to get
a list of the classes of the objects in the workspace, I can do this:
> sapply(ls(), function(x)class(get(x)))
a a1.df b d
"list" "data.frame" "integer" "numeric"
Now I want to get just the data frames.
> sapply(ls(), function(x)class(get(x))=="data.frame")
a a1.df b d
FALSE TRUE FALSE FALSE
However, I would like the names of the data frames, rather than the
True/False for the objects.
I've been trying all sorts of combinations/permutations with no success.
Any suggestions would be much appreciated.
Thanks,
Sincerely,
Erin
