Alternative to reShape

["Bert Jacobs" <b.jacobs@pandora.be>]

Using S-plus 6.2 for Windows XP

I have a dataframe that looks like this


Col1   Col 2
A      Alt1
A      Alt2
B        Alt2
B        Alt3
B        Alt4
C      Alt1

And I want to rebuild it like

        A       B     C
1       Alt1    Alt2    Alt1
2       Alt2    Alt3    0
3       0       Alt4    0

I've tried the reShape function in the library (Hmisc) but I don't have a
Colvar identifier. It is also unknown hom many alternatives there are but I
think atmost 10 for a category(A,B,C).

Any ideas how to do this?

Thx,
Bert
