Arguments
x
count of successes, length 2 vector of success
and failure counts, a formula, or a character, numeric,
or factor vector containing raw data.
n
sample size (successes + failures) or a data
frame (for the formula interface)
p
a vector of probabilities of success. The length
of p must be the same as the number of groups specified
by x, and its elements must be greater than 0 and less
than 1.
alternative
character string specifying the
alternative hypothesis, must be one of "two.sided"
(default), "greater" or "less". You can
specify just the initial letter. Only used for testing

conf.level
confidence level of the returned
confidence interval. Must be a single number between 0
and 1. Only used when testing the null that a single
proportion equals a given value, or that two proportions
are equal; ignored otherwise.
success

success. All other levels are considered failure.
data.name
