I would have, in NAMESPACE,
importFrom(methods, show)
exportMethods(show)
and
Ok, I could solve also the latter problem by defining show.myclass function
in the zzz.R file and adding the line 'S3method(show,myclass)' into

Thanks, the issue was solved by adding class definitions to the zzz.R file
in the R code directory. However, this led to a new problem.
The zzz.R now contains class definition:

and method definition for the new class, extending the generic 'show':

I have been trying to create an R package. This has been successfull until I
tried to define classes.
Currently, my procedure is the following:
Start R, load the function and class definition
>tmp <- function (x) {x}
>setClass("rpa", contains = "list", where=topenv(parent.frame()))
