Question

I would like to know how to quickly find the specific function called by a generic function for a specific object. Example :

library(spatial)
data(redwood)
K <- Kest(redwood)
plot(K)

This is not an usual plot, it’s a plot build for a Kest() object. So to investigate in order to find the function used, I do :

class(K)

I get

“fv” “data.frame”

I guess it is plot.fv

?plot.fv

Yey ! But I’m sure there a more efficient way than guessing. Anyone ?

Answer 1

You can find all of the corresponding generic functions for an S3 class using methods(). So in your case:

methods(class=fv)
