My problem is that when the data is merged it looks something like


Ind   L1     L1.1    L2     L2.1    L3       L3.1
a     12      13      NA     NA      NA      NA
a      NA     NA     22     43       34       45
b      14      15    45       64       NA      NA
b       NA    NA    NA      NA     99      84

Is there a way that I can merge the rows for each individual?

Cheers


Grant
