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.
