Please provide an example demonstrating this 'BUG', as we do ask you to do, along with basic information like your name, the version of R, the platform .... > It can be debugged in the following way: (Not in any sense of `debugged' that my dictionary mentions.) > 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$iterations. Why? The code contains a few lines earlier iterations <- if(family=="gaussian") 1 else control$iterations which is the intention. ?loess.control does say iterations: the number of iterations used in robust fitting. ^^^^^^ > I found also remarkable differences when comparing loess with PROC LOESS > (in SAS) using the same parameters and variables.
