Thanks for that, Vito.

Somehow, I often get lost in the whole slew of similar methods:
* get
* getMethod
* showMethods
* getAnywhere
* methods

Does anybody have a simple list of when to use which one?
And maybe I'm even missing some variants?

Thx.

Nick.

dear Nick,

getAnywhere("plot.glmnet")


Note the message you get when you type

methods(plot)
