Hi all,
I would like to transform to long format a matrix which has only
information about individuals and a value for each individual. I would like
to have it in ling format with more information related to groups, so ell
values and individuals are repeated for each group. Let me show the example:
matrix in wide format:
Individuals Value
A 3
B 4
C 5
D 2
And long format would be like:
Individuals Value Group
A 3 Group1
B 4 Group1
C 5 Group1
D 2 Group1
A 3 Group2
B 4 Group2
C 5 Group2
D 2 Group2
My case is of course very large so i thought this could be possible with
reshape function by adding a vector with the names of the groups or
something like that.
Thanks in advance.
