Hello, I'm currently using a tool that provides a Loess fitting, but I obtained results that are slightly different from those provided by R implementation of the Loess. That's why I would like to know if you could give me a source (bibliography or web) that explains in a clear way each step of the algorithm, with the possible options to choose, etc.. in order for me to understand those differences. Thank you, Naomi Berdugo.

The loess.demo function in the TeachingDemos package may help you understand what is going on. Note that the default for loess in R does an additional spline smooth/interpolation which may explain small differences from other tools.
