[R] Binom.test, vector input

All,

Is it possible to use binom.test with vector input for only one of the
arguments?  I was thinking that this would possibly work with sapply but
then it seems that the binom.test function would have to be re-written to
supply defaults for all other arguments.

set.seed(101)
sim.x = rbinom(100, 10, .8)  ## generate 100 values distributed B(10, .8)

# test of first sample against H.0: p=.6
binom.test(sim.x[1], n = 10, p = .6, alternative = "greater")

Is it possible to do the same test for all the rest without a loop or
re-writing the binom.test function?

Cheers,
David
