R-experts:

A quick question, please.

>From a lab exp, I got 12 positives out of 50.
To get 90% CI for this , I think binom.test might be the one to be used.
Is there a better way or function to calculate this?

> binom.test(x=12, n=50, p=12/50, conf.level = 0.90)

        Exact binomial test

data:  12 and 50
number of successes = 12, number of trials = 50, p-value = 1
alternative hypothesis: true probability of success is not equal to 0.24
90 percent confidence interval:
 0.1447182 0.3596557
sample estimates:
probability of success
                  0.24

thx much
