Hi all,
I am not that much skilled in C/C++ programming, but I
am eager to learn more about it.
I have a problem to manipulate the following data set.
I hope that I may get a help from you guys!
I am looking for an algorithm that transpose(merge) a
data set by a variable. The data set is a two
dimensional x(m,n). If the the value of the first
column is equal to the value of the previous row (m,1
=m-1,1) then merge the variables of ( m, 2-n) to the
first row.
May be an example of a data set explain in a better
way.
obs v1 v2 v3
1 11 12 13
1 21 22 23
2 22 23 24
3 44 45 46
3 55 54 56
3 66 65 66
The transposed(merged) data file would look like
1 11 12 13 21 22 23
2 22 23 24
3 44 45 46 55 54 56 66 65 66
Any help is highly appreciated in advance
Ashe
