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!
