Hi, I'm requesting you don't berate me for asking this question:

I clearly don't have the gist of factors.

I have two dataframes, A and B.

Each of them has a column containing strings (they're labels).

I want to, one-by-one in a loop, compare the particular string in an entry from dataframe A to an entry in B, to see if they're the same.

The problem, when posing the question:
searchID1 <- A[['label']][i]
possMatch1 <- B[['label']][j]
searchID1 == possMatch1

I get the error:
Error in Ops.factor(searchID1, possMatch1) : 
  level sets of factors are different

I presume this is because the set of possible values in the 'labels' columns, respectively in A and B, differ.  In my case, I'm not interested in this at all; I just want to compare individual entries from the two dataframes in a pair-wise fashion.

Can I strip the "factors" associated with the entries?  Is there a better way?

Jonathan
