Dear Paul, I am dealing with this kind of problems right now, and if I am not wrong, when you want to apply an adaptative bandwidth, you should introduce a value for the "adapt" parameter instead of for the "bandwidth" parameter. This value will be between 0 and 1 and indicates the proportion of cases around your regression point that should be included to estimate each local model. So depending on the amount of points around each case, the model will use a different bandwidth for each point to be fitted.
Related to your question, do you know what is the influence of the data introduced in the "data" parameter to the data to be fitted (introduced in the "fit.points" parameter)? I mean, you have to obtain new local models (one for each point to be fitted), so I do not understand whether the "data" parameter is used somehow...
