Outlier detection library/package

[Budana_Prijadi@fmi.com]

Dear S users,

 

I am posting this message to R-help also.

 

Is there a free library (or package) containing functions for S or R that detects outliers for Gausian and non-normal data?

I also learnt a method where we transform the data log naturaly before using Gausian outlier identification.

 

Besides standard Boxplot methods, I would like to compare with GESD Many-Outlier Procedure, Shapiro-Wilk W, Dixon etc. etc.

 

I am surprised that with a topic as important as "Outlier analysis", I have not found any packages/library sources pertaining it (or did I not search good enough?).

 

I am using Windows based R 1.6.1 and S-PLUS 6.1

 

Many thanks,
