Is there general documentation on a procedure to follow to: (a) Find what methods are available for a particular class of objects?
(b) Find what classes of objects have methods defined for a partilar generic function? (c) Get the code that's actually used? For example, I recently needed to access numbers associated with an object of class "lmer". Sundar suggested I use with 'getMethod("show", "summary.lmer")'. However, this doesn't work with the example below. Thanks, spencer graves Francisco J.
