Dear list,
I am trying to look at the function inside a package.  I know that
methods() would do the trick, but what if the function is hidden?  I have a
problem displaying the hidden function.

Say, for example the MCMC package.  How do you view the code of that
function?
You can use the prefix MCMC:::foo to display the foo function from MCMC, 
whether or not it is exported.

something like this:

which
function (x, arr.ind = FALSE, useNames = TRUE)

{

     wh <- .Internal(which(x))

     if (arr.ind && !is.null(d <- dim(x)))

         arrayInd(wh, d, dimnames(x), useNames = useNames)

     else wh

}

<bytecode: 0x1021eef50>

<environment: namespace:base>

This is R FAQ 7.40, and that document gives some good pointers:
http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-do-I-access-the-source-code-for-a-function_003f

I prefer to simply download the source code version of the package
from CRAN, so that comments aren't stripped, but there are several
other options.

It might be a C code wrapped around.
