[R] confidence intervals on multiple comparisons

[Salvatore Enrico Indiogine]

Greetings!

I am using prop.test to compare 4 proportions to find out whether they
are equal.  According to the help function you can not have confidence
intervals if you compare more than 2 proportions.

I need to find an effect size or confidence interval for these proportions.

Any suggestions?

Enrico
