Thank you for your reply, Prof. Ripley. > > - 'function' (if() and + are functions in R, so do you want those?) I was thinking about functions that are used like this: foo() So I don't need things like "names<-". I don't need functions like +. -, $, as I can highlight the separately if desired, though I'm not doing this at the moment. Functions like for() while(), if() function() are handled separately. > > - 'a base R installation'? What is 'base R' (standard + recommended > packages?) And on what platform: the list is platform-specific? Yes, I mean standard + recommended packages. As for platform, most of my intended audience will be MS Windows users, though I am using Linux (Fedora) to generate this list (i.e. my R installation is on Linux). > > Here is a reasonable shot: > > findfuns <- function(x) { > if(require(x, character.only=TRUE)) { > env <- paste("package", x, sep=":") > nm <- ls(env, all=TRUE) > nm[unlist(lapply(nm, function(n) exists(n, where=env, > mode="function", > inherits=FALSE)))] > } else character(0) > } > pkgs <- dir(.Library) > z <- lapply(pkgs, findfuns) > names(z) <- pkgs Excellent, that works just fine for me. I can edit out certain packages that I don't expect to use, before formatting as desired. I can also use this function on a library of packages that I use regularly and will be using in the web pages. > > I don't understand your desired format, but > > write(sQuote(sort(unique(unlist(z)))), "") I wanted a single string "...", with entries enclosed in "''" and separated by "," (this is to go in a PHP array). I can generate such a string from your z, above, as follows: paste(sQuote(sort(unique(unlist(z)), decreasing = TRUE)), collapse = ", ") > > gives a single-column quoted list.
