Is it -prtest- or -prtesti-?

That was my first impulse. However, the documentation refers to "Two-sample test of proportion." From the examples, I got the impression it was for unpaired samples. ttest, by way of contrast, refers to "Two-sample mean-comparison test (unpaired)" and "Two-sample mean-comparison test (paired)". So, ttest lets you do something like a before and after comparison of the same subjects; prtest sounds to me like it is comparing proportions for two different samples, rather than paired values.
