binom.test(x, n, p=0.5, alternative="two.sided")
"two.sided" (not equal to
p),
"less" (less than
p) or
"greater" (greater than
p).
class attribute
"htest",
representing the result of binomial test:
The exact probabilities are computed for the binomial distribution.
The probability of success is equal to
p.
x
is the number of successes out of
n independent trials, each with the
same probability of success.
