I want to create an excel file where there are three columns
proteinA pp protein B
I have acquired the word file as follow from biogrid:
"ETG18033 ETG19698 Nfkb1 Relb NF-KB1|NF-kappaB|NF-kappaB1|p105|p50|p50/p105 shep Two-hybrid Ravasi T (2010) 20211142 10090 10090"
I want to process the file such that only proteins names are taken.
I am not so familiar on working with string. I wanted only protein which are
RelB i.e. the first two protein. How could I proceed with R platform?
