[R] more about outer

[Erich Neuwirth]

this is my current answer to my own question.
should we have such a funcion in a more general version
(i.e. with an arbitraty number of argument lists, for n-ary
functions)
in the core language?

myouter<-function(x,y,fun){
t(sapply(x,function(arg1) sapply(y,function(arg2) fun(arg1,arg2))))
}
