I'm using this syntax to create data subsets for plots: subset=source=="Both". Now I would like to create a subset defined by two different variables like this: subset=source=="Both" subset=site=="home" but this syntax is not correct. The documents in the manual for subset seem to be creating whole new data files not just selecting rows based on the contents of the variables. How do I subset based on two variables.
