search for: optionalfunct

I was surprised to notice that statements like: h = function(...){list(...)}(x=4) do not throw syntax errors. R claims that 'h' is now a function, but I can't seem to call it. > h = function(x){list(x)}(4) > is(h) [1] "function" "OptionalFunction" "PossibleMethod" > h() Error in list(x) : 'x' is missing > h(4) Error in h(4) : attempt to apply non-function > What's going on?
