Hi, I have a problem in which I have test score data on students from a number of schools. In each school I have a measure of whether or not they received special programming. I am interested in the interaction between school and attendance to the programming, but in a very select set of comparisons. I'd like to cast the test as one in which students in each school who attend are

Hello all - I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . .

Hi, I couldn't figure out how to use the functions from the ctest library. I'm using the r-base package that comes with debian potato. library("ctest") told me that no such package existed.
