Concatenate values in a column
Seems like this should be simple, but I cannot find a clear example. I would like to concatinate the values in columns of a specific name("ROW" and "COL") and create a new column with the result in it. Example below. ROW COL CELL5 1 5_13 2 3_212 -1 12_-1 best shot at code so far: column("ROW") << Data type(Character); column("COL") << Data type(Character); //a = {column("ROW"), column("COL")}; ...
