I don't know anything about poly(), but in most cases where I've needed to draw fitted curves (e.g., when doing spline fitting), it turned out that there was a version of the predict() method defined for my object, and that was what I needed. I see that there is some sort of predict() defined on poly objects; does it help? -- Nathaniel -- Electrons find their paths in subtle ways. _______________________________________________ R-lang mailing list [email protected] http://pidgin.ucsd.edu/mailman/listinfo/r-lang
