I can't vouch for the best way, but here is one way, return a list of the
values

multipleoutput<-function(x)
{
	squared<-x^2
	cubed<-x^3
	exponential<-exp(x)
	factorialVal<-factorial(x)
	return(list(squared=squared, cubed=cubed, exponential=exponential,
factorialVal=factorialVal))
}

Hope this is helpful,

Dan
