[Rd] LOESS (PR#9064)

Hello,

I found a little BUG in loess <stats>. It does not receive the iterations parameter.
It can be debugged in the following way:

THIS IS AN EXCERPT FROM THE CODE: ....

fit <- simpleLoess(y, x, w, span, degree, parametric, drop.square,

        normalize, control$statistics, control$surface, control$cell,
        iterations, control$trace.hat)

Replace argument iterations with control$iterations.

I found also remarkable differences when comparing loess with PROC LOESS (in SAS) using the same parameters and variables. It really confuses me. Where can I report this?

Best regards,

Felix Lamp
