hello all I am writing a quite simple script to study dental wear patterns in humans and I wrote this function sqrt(var(Y1)+var(Y2))^2-4(var(Y1)*(var(Y2)-cov(Y1,Y2)^2)) but appear this error message Error: attempt to apply non-function
Write 4*( instead of 4( assuming you want to multiply.
alternatively I wrote this sqrt(var(Y1)+var(Y2)^2)-4[(var(Y1)*(var(Y2)-cov(Y1,Y2)^2))] but this error message appear [1] NA Warning message: NAs introduced by coercion
[ is an indexing operator. You are trying to index the number 4. Which is impossible. Berend
some suggestion to solve this?? thank you so much for your help Miguel [[alternative HTML version deleted]]
