> Currently, the transform operation allows one to consume a frame containing strings and replace the strings with integer IDs. However, there is no operation that provides the inverse of this functionality. In other words, it would be nice to have an operation that allows one to use a recode map produced by a previously invoked transform operation and replace the integer IDs with the corresponding strings provided in the recode map.
