[R] probability of binary data

[Irucka Embry]

Hi, how are you?

I am trying to replicate the binary data f(2) function in the attached
document by starting with the simple example found below:

observed <- matrix(c(0, 1, 0, 0, 1, 1, 1, 0, 0),3,3,byrow=TRUE)
data <- matrix(c(1, 1, 0, 0, 1, 0, 0, 0, 1),3,3,byrow=TRUE)

f2 = sum(probability of the matrix element where the matrix element is
present in both the observed and the data)/[sum(probability of the
matrix element where the matrix element is present in both the observed
and the data) + sum(probability of the matrix element where the matrix
element is present in the observed and absent in the model) +
sum(probability of the matrix element where the matrix element is absent
in the observed and present in the model)]

What is the best way to create the f2 function in R?

Thank-you.
