[R] Finding Zeros of a Function

Dear All,
I need to find the (possible multiple) zeros of a function f within an 
interval. I gave uniroot a try, but it just returns one zero and I need 
to provide it with an interval [a,b] such that f(a)f(b)<0.
Is there any function to find the multiple zeros of f in (a,b) without 
constraints on the sign of f(a) and f(b)?
Many thanks
