*.R files for user libraries

Hi!

The Writing R Extensions document (R-exts.pdf) states that,
for creating an R library,

""
The `R' subdirectory contains R code files. The code files to be installed
must start with
a (lower or upper case) letter and have one of the extensions `.R', `.S',
`.q', `.r', or `.s'.
""

Does this mean that each function sould go into
a separate *.R file?

I understand that I can save a given function as

save(test,file="R/test.R")

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

But I have many functions, should I make that each function
go to a separate file? Is there any utility for doing
this?

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.
