Hello all!
I have a problem with R. How can I do this assemble the ELM PRP for each ua.
My data is like this:
ua ELM PRP 122C MO 5 122C BR 3 122C FA 1 122C MO 1 122D BR 7 122D MO 2
122D BR 1
and I want to obtain something like this:
ua ELM PRP 122C MO 6 122C BR 3 122C FA 1 122D BR 8 122D MO 2
Thank you very much!
