Methods selection for an inherited S4 class
Multi tool use
My question is how to apply the generic function plot() using my new method for my inherited S4 class.
I extend the existing S4 class (whose name is stanfit) in rstan, say lowerS4class, and define a new method for generic function plot for the extended (inherited) S4 class, say upperS4class.
But the following undesired selection (i.e. the selected method is the method
for the lower S4 class) occur with the following Note in the R console when I apply the generic function plot() for the extended S4 class.
Note: method with signature "lowerS4class#missing" chosen for function ‘plot’,
target signature "upperS4clss#missing".
"upperS4clss#ANY" would also be valid
By the following, The generic function plot() choose for new method for upper class:
plot( x ,signature("upperS4class"))
But I do not want to assume that users for my package know the name of S4 class. By the following, the new method is also chosen: (Why ?)
plot( x ,signature("lowerS4class"))
But the following the method from another package for lower class is used.
plot( x )
Edit for comment-----------------------------------------
Inheritance
setMethod("plot",
signature(x = "upperS4class"),
definition = function(x){
foo(x)
}
)
where foo is a function defined by me.
Def. for upperS4class
upperS4class <- setClass(
#Name for upper class
"upperS4class",
# Inheritance
contains = "lowerS4class"
# New slots
representation(
.....
),
# Initial values for new slots
prototype(
.....
),
)

Could you post your method definition (or a skeleton of it)? Is the method defined for signaturex=upperS4class,y=missingor justx=upperS4class? (I am also assuming your class definition starts withsetClass("upperS4class",contains="lowerS4class",...) -> upperS4class)
