dear s-plus-users,

in a scatterplot, i want to smooth data via least squares but don't want
to smooth all observations but perform the smoothing separately on say
two groups, thus ending up with two lines. couldn't find any solution to
this problem so far. any suggestions would be highly appreciated,
thanks.
