R help - Jan 2006 - Can I ask for the C code inside an R function using .C?

Hello, all,

It is a general question, but I couldn't find the answer elsewhere. 
I am using an R function using .C but don't understand one of its
behaviors without the C code. I am wondering the so-called 'open
source'. It doesn't include the C code together with the R function,
does it? So what I want to ask is whether it is justified, possible or
polite to ask for the C code behind the R function.
Sorry if I miss anything! Thank you as always!

Regards,
Yingfu

Source code for R and all CRAN packages are on CRAN.  If you want the C or
Fortran code used in R or add-on packages, you need to download the source
(the .tar.gz files).  You won't see the code if you just install the binary.

You can download the source from any package from a CRAN mirror near you and
the src directory will contain the source code of the included C and fortran
functions.

Just wondering:  How do people with slow connections get R?  The Windows
binary is about 25MB, while the source .tar.gz is only 13.7MB.
