Hi
you can check the package “extremevalues” . The methods you mentioned are modelling methods and the outliers detection happens before to use those methods.
The book of reference is “Outlier Analsysis” by Charu Aggrawal you can perhaps find in university library, no R there but very good explanation and formulation.

Hope this help.
