Probably these are non-exported functions. Try:
Or if you know which package a function comes from:
<package name>:::<function name>

> Subject: [R] Looking up the code for a function
> Hi all,
> I am trying to find out how a certain functionality is implemented in R
> respectively what a certain found does exactly.
> Specifically I am interested in multivariate kernel density estimation.
> I found the "ks" package and its "kde" function. Usually, my preferred
> way to "look under the hood" of any function is to simply type the
> functions name without any brackets or arguments, in this case just:
> kde. And this works fine for kde itself. But kde calls other functions,
> such as kde.grid.3d or kde.points and typing those function names just
> yields "Error: Object '[function name]' not found". These functions
> aren't defined within kde either (as far as I can see).
> So here is my question: Am I doing something wrong? Is there a way to
> look up the code of these functions?
> (I already tried google but found only the usual documentation
> (vignettes) and articles referencing the function kde or the package ks).
> Thanks a lot in advance
