AW: [R] binom.test appropriate?

[Lüdde Mirko]

No, 

since I'd like to test 

	null: p <= p0
	alternative: p > p0. 

and my understanding is that binom.test tests

	null: p = p0 (can only be a "simple" null hypothesis 
			according to help(binom.test))
	alternative: p > p0 (or p < p0 or p != p0). 

Thanks, Mirko.
