Hi William, This worked like a charm! I was thinking about using reshape(), but was unsure on how to approach it. Though I have a whole lot of variables, I decided to keep only those variables that contained both sexes' characteristics, reshape it into wide format, and merge with the rest of the data later and it worked perfectly.
Thanks you guys so much. All ideas were great and I greatly appreciate your help!!
