I want a data frame (derived from another data frame) of the form
Type Set
1 {1,5, 7}
2 {3,8)
.. ....
tapply(Id,Type, set) works, but does not yield a data frame.
'set' is from package set/set6/etc
ddply does not seem to work with the function.
How should I proceed with this optimally?
Thanks and Best
A Mani
