I've written a function, myFunc, that works fine with myFunc(data,

apply(myArray, 1, myFunc, ...)
I get a strange error:
Error in match.fun(FUN) : '1' is not a function, character or symbol
which really puzzles me because '1' is meant to be the margin of the
array I want to apply over, but how come does apply() treat it as a
function?
I have been successfully using apply() for a while, so I must have
made a stupid mistake this time. Hopefully somebody can point out
something obviously wrong without me providing any details of the
function.
If you want any help you will have to give a reproducible example.
Have you tried traceback()?
Have you tried making a local copy of apply() and putting in a call
to browser()?
Have you tried using debug()?
Sheesh!
cheers,
