The instructions below are for examining files from a source code file. For package binaries, the R code may be in a binary file (.rdb).. Then the following will help.
The first thing to try is to Download and install the package and type library(packagename) Type the function name (without the ()). All exported functions will be visible (export commands in the NAMESPACE file of each package). In a compiled packages, some internal functions may not be "exported" and be visible.

First download the Program R package containing the function. Specifically, download the file that ends in "tar.gz". This is a compressed file. Expand the compressed file using, for example, "WinZip". Next open the uncompressed file that ends in ".tar". I was able to open that file with the free software "7-Zip" available on the internet. After installing that software I clicked on the file "7zFM.exe" and navigated to the directory containing the ".tar" file. You can extract the contents of that ".tar" file into a new folder. The contents consist of R files showing the source code for the functions in the R package. These R files can be opened with a text editor. Hopefully, it is okay to mention other software here by name. I have used the above method twice in the last few months to view source code for functions. In both instances I needed a substantial amount of time to figure out how to do it. This post might help others and perhaps will help myself in the future. Mark W.
