Hi all, I have a file of this kind: entry0001:AB0032,CF32134,DF34334 entry0002:AB0033 entry0003:AB0032,CF32134,DF34334,DD343434,DD34222 entry0004:AB0032,CF32134 And I would like to read it into something like a hash, so that I can then loop over it by keys and values. I wonder which would be the best way to do that in R? Thanks, Albert.
