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.
