[R-pkg-devel] loadMethod() not available with Rscript

Dear all,

Could someone explain this to me? I have a simple script (see below).
my_function() is an S4 method. The package imports all functions from
methods that it uses.

When I run the script in a vanilla R session it works. When using
Rscript I get the error: Error in loadMethod(function (x, ...)  :
could not find function "loadMethod"

loadMethod() is NOT used in mypackage and not imported.

library(mypackage)
my_function()
