R help - Dec 2011 - cannot access the functions in the package

hi, I am using the package of "Fslector" which contains a function
named
"information.gain". I want to see the detailed code of this function.
the
result shows
> information.gainfunction (formula, data)
{
    information.gain.body(formula, data, type = "infogain")
}


When I then try to see the code of  information.gain.body, it shows
Error: could not find function "information.gain.body".


Why cannot I get access to the codes?

Thanks in advance!

You probably need to use Fslector:::information.gain.body, or (even 
better) look at the source for the package, which you should be able to 
get using

download.packages("Fslector", type="source",
destdir=<your directory>)
