in function reference about mean function there is :
Arguments:    x  (series or list)
        partial  (boolean, optional)

Can you give me an example including partial (a boolean condition), please?
Does this mean that I can calculate the mean of a variable in a subsample (defined by a boolean condition) without using the smpl command?
