The package.skeleton() function is intended to be used once as a quick
setup of a new package; you shouldn't be using it routinely.  After the
first quick setup, you should edit the source of the package to get what
you want.

A few more comments inline...

The code above doesn't make sense in a package:  either you created the
environment, or you didn't.  That code will look through attached
packages, and if one of them has a variable of that name, will try to
remove it (but will likely fail to do so).

This says that you read the file d:/probando/probando.r, then created a
package in the same directory.  Don't do that.  Create the package
somewhere else, and copy the source to your functions into the R
subdirectory that gets created.

As far as I can see, you never added this to the package, so the
environment wouldn't be created.
