All of these tries leave to the same result:
1) First I defined kmeansnew with the content of kmeans, but leaving
the <environment: namespace:stats> out.
Then I run environment(kmeansnew)<- environment(stats::kmeans) at the
command line.
2) kmeansnew <- kmeans() {.... environment(kmeansnew)<-
environment(stats::kmeans) }
3) kmeansnew <- kmeans() {....} environment(kmeansnew)<-
environment(stats::kmeans)
When I do kmeansnew(iris[-5],4) it returns:
Error in do_one(nmeth) : object 'R_kmns' not found
'R_kmns' is a .FORTRAN that is called by the original kmeans().
it is the same error as if i would just leave <environment:
namespace:stats> out.
