Hi all, I think this is a very basic question, but I'm new to this so please bear with me.
I'm using match to translate elements of a data frame using a lookup table. If the content of a particular cell is not found in the lookup table, the function returns NA. I'm wondering how I can just ignore those cells, and return the original contents if no match is found in the lookup table.
