Hello Vitalie,
your function now works. Noticed though that I had to replace all "_" by
".", the "_" is not allowed in Splus it is still reserved, although
obsolete, for assignement. Here is the output of the function for three
functions, the last one being an home function.
> funnargs(colMeans)
(list "S+" '(("x" . "") ("..." . "")) )
> funnargs(glm)
(list "S+" '(("formula" . "formula(data)") ("family" . "gaussian") ("data"
. "sys.parent()") ("weights" . "") ("subset" . "") ("na.action" . "")
("start" . "eta") ("control" . "glm.control(...)") ("method" .
"\"glm.fit\"") ("model" . "F") ("x" . "F") ("y" . "T") ("contrasts" .
"NULL") ("..." . "")) )
> funnargs(frequence)
(list "S+" '(("object" . "") ("maxsum" . "100") ("sorting" . "F")
("weights" . "NULL")) )
Thanks,
Gérald
