Hi All,

I have a table based on ordial data and i want to compare proportions and i've seen in the pwr package i can use

however i want to find out what the sig. value is based on n1,n2,p1,p2 and this package doesn't contain this..
Does anyone know of a package that does or is it a case of writting a function specifically for this?

Many thanks in advance
