you may find RSiteSearch() and help.search() functions useful for this

Subject: [R] Were to find appropriate functions for a given task in R

This is a generic request concerning were to look for finding
appropriate information on a precise procedure in R.
I'm using R for teaching introductory statistics and my students are
learning how to deal with it. However, I find it difficult to locate
some of the procedures. For instance, for basic crosstabulation, it is
obvious that basic functions as table, ftable, and prop.table can be
used. But there is a CrossTable function that is very useful. This is
hidden in gmodels and gregmisc, as far as I've been able to explore 
packages. However, there is no way (unless I sit down to r-help for
hours) to be sure if there is some other place in which a very useful
function is hidden for table manipulation (for instance controlling 
other variables). This is only an example. But there are many more. 
to look for CI for proportions? I can find it but it is not easy.

I understand R is more appropriate for difficult statistical 
(glm and similar), BUT students need to start somewhere..

My specific claim is about the need for a sort of guide in which the
different procedures could be classified (and some redundancies could 
deleted...by the way). Is there something similar around? Any project
working on this? Any clue for?

If not, I would suggest starting some kind of easy reference based on
the problem to solve. This could indicate were to look for. Last day I
find in package vcd that a function exist for testing the
goodness-of-fit of a sample to binomial and other distributions..but
this was VERY difficult to locate.

Any way, as usual, any indication will be very useful (spaecially for
