R help - Sep 2009 - medcouple-based outlier detection in R

I need to detect outliers in a large data set which is highly right-skewed. I
plan to use medcouple-based outlier detection. Is there any support for
medcouple-based outlier detection in R? Are there any other routines in R to
perform outlier detection in highly right-skewed data?

library(sos)  # a package that links to Baron's r-search
???medcouple

7 hits in 2 different packages (robustbase and LambertW)
So I would guess that the answer is "yes".

Yes. Suggest you look over the Robust Statistics Task View.
