[R-pkg-devel] tools::checkReplaceFuns gives results I don't understand

[Richard M. Heiberger]

I think this is related to the difficulty I wrote about last week.
This example is with last night's development build and uses only
R-core provided code.

I don't understand this Error message

Error in get(f, envir = code_env) : object '[<-.ts' not found

when I can display the object stats:::`[<-.ts`

I am hoping this is related to these messages that I receive when I do
R CMD check on my package:

* checking replacement functions ... WARNING
Error in validObject(.Object) :
  invalid class "ObjectsWithPackage" object: superclass "atomicVector"
not defined in the environment of the object's class
Calls: <Anonymous> ... metaNameUndo -> new -> initialize -> initialize
-> validObject
Execution halted
The argument of a replacement function which corresponds to the right
hand side must be named 'value'.
