I think you are asking to see what I call the source code for a function in a package. If so, the way I do it is as follows, which has worked successfully for me on the three times I have tried. I keep these instructions handy in a few places and just copied and pasted them here:

To see the source code for a function in Program R download the 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". Now you need to open the uncompressed file that ends in ".tar". Download the free software "7-Zip". Click on the file "7zFM.exe" and navigate 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.

EDIT:

Today (July 8, 2012) I was able to open the 'tar.gz' file using the latest version of 'WinZIP' and could copy the contents (the source code) from there without having to use '7-Zip'.

EDIT:

Today (January 19, 2013) I viewed the source code for functions in base R by downloading the file 'R-2.15.2.tar.gz'

To download that file go to the http://cran.at.r-project.org/ webpage and click on that file in this line:

"The latest release (2012-10-26, Trick or Treat): R-2.15.2.tar.gz, read what's new in the latest version."

Unzip the file. WinZip will work, or it did for me. Then search your computer for readtable.r or another base R function.

agstudy noted here https://stackoverflow.com/questions/14417214/source-file-for-r-function that source code for read.csv is located in the file readtable.r, so do not expect every base R function to have its own file.
