categorized complete list of R commands?

every time I read the R release notes for the next release, I see many
functions that I had forgotten about and many functions that I never knew
existed to begin with.  (who knew there were bibtex facilities in R?
obviously, everyone except me.)

I wonder whether there is a complete list of all R commands (incl the
standard packages) somewhere, preferably each with its one-liner AND
categorization(s).  the one-liner can be generated from the documentation.
I am thinking one categorization for function area (e.g., "programming
related" for, say, deparse; and "statistical model related" for lm; and
another categorization for importance (e.g., like "common" for lm and
"obscure" for ..).  Such categorizations require intelligence.

if I am going to do this for myself, I think a csv spreadsheet may be a
good idea to make it easy to resort by keys.
I don't think all if those exist already, but the help system gives indices for each package and, within the core packages, things are relatively well categorized simply by knowing the package they're in. Not a full answer, but perhaps saves you a bit of time.

Here's a categorisation of all the functions in base and utils that I
made recently (not sure if the csv will survive posting the list).
Feedback welcomed - this was just a quick first pass, and it's not
authoritative.

A categorized list of functions would indeed come in handy.
So, based on Michael Weylandt's lines, I gave it a try:
#  categorize functions.R
#  Franklin Bretschneider
#  after R-help: R. Michael Weylandt
#  05-04-2013
#  =========================
nprint <- function(x) print(x,quote=FALSE)
allfuncs = unlist(sapply(search(), ls))
names(allfuncs) <- NULL
patterns = c("print", "plot", "axes", "axis", "color", "file", "read", "write", "load", "save","wave", "image", "table", "data", "apply", "title")
patterns = sort(patterns)  #  optional
n = length(patterns)
nprint("     ")
nprint("     ")
for (i in 1:n) {
	nprint("     ")
	nprint(paste("Functions with",patterns[i],":"))
	      nprint("===============")
	nprint(allfuncs[grep(patterns[i], allfuncs, ignore.case=TRUE)])
	nprint("- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -")
	}
nprint("     ")
nprint("     ")

The list of keywords can be adapted to one's own wishes.
Maybe this helps.

Best wishes,

Franklin

Try the 'sos' package. Not exactly what you ask, but close: once you
supply a keyword.
