Hi all,
I am writing a function (fun.R), but I dont know how to code the
function so that the Help Text will be shown up when one types ?fun (of
course, after he loads it up). Anyone has any advice for me how to do
that?
The help text is separate from the function (unless you use the
roxygen package or similar). You need to write a package so that R
will find the help; instructions are in the Writing R Extensions manual.
I was expecting something simpler than writing a package, and that I can
integrate it into fun.R, but thanks anyway.
(a) Writing a package is not all that hard.
(b) It focuses the mind wondrously.
It's not at all like being hanged!

(c) Using R CMD check on the package is very useful for picking the
lint off the code.
cheers,
Rolf Turner
