functions with two results

["Dakin, Jonathan" <j.dakin@ic.ac.uk>]

Could anyone tell me the best way (or any way) to retrieve the output of a
user-defined function, when it generates two data frames ?  

(The function splits one large dataset into inliers and outliers according
to a dataframe of values passed as a second parameter.)

I'm using splus 6.0 professional release 2 under W2K.

Many thanks
