[R] Glossay of available R functions

If I understand correctly what you need, this is already available through
the main help page. If you type help.start() to get to the html help, then
follow the link "Packages". This will give you an index of all available
packages installed on your system (base + contributed). Clicking on any of
the package names will give you a list of available functions in that
package. This is a nice way to present a categorized index of several
thousand functions. An additional advantage is that this index will be
updated if you install more packages on your system.
Hope this helps.

You get a list of objects (not just functions) in the base package. You can
also get a list by library(help=base).
However, that is far from all the functions available in base R.
As a quick check
as.matrix(sapply(search(), function(x) length(ls(x, all=TRUE))))
so it is less than half the objects loaded and visible in a default session.
And there are another 18 packages shipped with R.
Looking at a list of 2300 objects is daunting, and so we provide search
facilities (including via the HTML pages).

Which index page? If you mean that given by help.start(), it is not a
common request, and search is linked from there.
