The S3 methods defined are unclear #43
Description
The methods defined are unclear given the code and its comments which has:
method for class 'data.frame' :
interplot.plot <- function(...)
method for class 'lm' and 'glm' :
interplot.default <- function(...)
The generic function method is also confusing and seems error prone / not compatible with the different classes and methods systems in R as well as class inheritance.
