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 and kind regards RK ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
