True, but reading the supplied help is appropriate before contacting the maintainer.



and click the link to the index and find the autoplot method in the list and follow that link. 

Or you can read the help for the "pam" function and discover that the class of the returned object is "pam" so you can use


to go right to it. If the documentation doesn't answer your question you can communicate that to the maintainer.

You can also just enter


at the console and read the source code if it is written in R to see what calculations are being done.
