Dear useRs, Some time ago I queried the list as to an efficient way of building a function which acts as ls() but with a different default for all.names:
http://tolstoy.newcastle.edu.au/R/e6/help/09/03/7588.html I have struck upon a solution which so far has performed admirably. In particular, it uses ls() and not its explicit source code, so only has a dependency on its name and the name of its all.names argument. Here is my solution: lsall <- function(...) { thecall <- as.call(c(as.name('ls'), list(...))) newcall <- match.call(definition=ls, call=thecall) if( !('all.names' %in% names(newcall)) ) newcall[['all.names']] <- TRUE eval(newcall, envir=parent.frame()) }#### end lsall In my hands this function has always acted exactly as I expected, identically to ls() but with the default of all.names=TRUE (which can be overridden as usual). In particular, it (i) gets the proper search path position right; (ii) works as expected within a browser() session. I am sharing this in case someone finds this construction helpful for other purposes, and in case someone finds a failing case they then have the option of communicating it back here.
