R how to use files in the same packages

I am planing to do all my R scripts in the same package in order to move it easily between my friends.

What I have done is created an R packages using R studio and the following files have been automatically generated:

projectName.Rproj
DESCRIPTION
man
NAMESPACE
R
Read-and-delete-me

I created a new R script and I save it in R folder. Now I want to add a new R script that uses functions that have been defined in the first script.

I created this new script and I tried to use on of the functions that are located in the other script. I got error that the function is not defined.

What I tried to solve the problem

I used the source command in the beginning of the new script like this: source('something.R') I got error message that something.R doesn't exist.

What is the solution please to include functions that exist in a different scripts ** but in the same packages**?

Note

I don't want to use relative paths because I want the package to be as portable as possible

Thanks a lot

You appear to misunderstand how package works: by having a file with a function in the R/ directory, it is already visible to other code in the package.

If you want to make it available to other packages, you can control this via the NAMESPACE file. All this is well-documented in Writing R Extensions which comes with your copy of R, and a number of additional books and tutorials you could peruse.
