Hi, I know I can do this with a for loop with strsplit and grep, but is
there more efficient way?
Given a data dataframe (input) and a category column (lst),
> input
item loc
1 item 1.1: earnings <sep> item 1.2: w2 <sep> shelf 1
2 item 1.3: deductions drawer 1
3 item 1.1: earnings shelf 2
> lst
item cat
1 item 1.1 A
2 item 1.2 B
3 item 1.3 C
how to get a result frame like
> result
item loc cat
1 item 1.1: earnings <sep> item 1.2: w2 <sep> shelf 1 AB
2 item 1.3: deductions drawer 1 C
3 item 1.1: earnings shelf 2 A
Thanks,
Richard
