No, no, no. This saves a binary version of the file. You need to use

One file or many is ok. Most people find it easier to write the functions
in .R files to begin with, but the new 1.3.0 has an experimental function
package.skeleton() that does some of the work of setting up a package.
It is easier to find things in the documentation if you use our
terminology: you are trying to create a package, not a library. A library
is a place to put packages.
