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.
Number 1 is what you should do. When you do that and print kmeansnew in
the console, does it list the environment at the end? What does
environment(kmeansnew) print?

Thank you both.
1) As Duncan said, if I leave<environment: namespace:stats> out, it
will not work since it is using .C and .Fortran functions that kmeans
calls.
I
2) don`t know how to use the as.environment() (I did not understood by
reading the help).
3) Setting environment(kmeansnew)<- environment(stats::kmeans) does
not work as well.
I think you need to explain what "does not work" means. What did you do,
and how do you know it didn't work?
4) Using fix() works, but then I don`t know how to store just the
function in an external file. To use it in another computer, for
example. If I use save(myfunc,"myFile.R", ASCII=TRUE) it doesn't work
when I try to load it again using myfunc=load("myFile.R")
Don't use load() on a source file. Use load() on a binary file produced by
save(). You could save() your working function, but then you can't edit it
outside of R. To produce a .R file that you can use in another session,
you're going to need to produce the function, then modify the environment,
using 2 or 3 above.
