binom.test appropriate?
...there,
as part of a 2 x 2 contingency table analysis I would like to estimate
conditional probabilities (success rates) in a Bernoulli
experiment. In particular I want to test a null hypothesis p <= p0
versus the alternative hypothesis p > p0.
As far as I understand the subject, there are UMPU tests for these
types of hypotheses.
Now I know about R's "binom.test" but the help text is telling me it
will test only simple null hypotheses of the form p = p0.
Could someone please give me a hint whether there is a suitable test
or about what I got wrong?
Thanks, Mirko.

Fisher's Exact Test
Appology in advance if this has been asked and answered. I am getting different
answers using Fisher's exact test in the package ctest. For example:
x_cbind(c(8, 22), c(31, 29))
fisher.test(x)
Fisher's Exact Test for Count Data
data: x
p-value = 0.04024
alternative hypothesis: two.sided
However, in SAS or other packages on the net the answer I get is p-value=
0.02664.
Is this
