Hi:
The idea is as follows:
* string your four matrices into vectors, cbinding them so that the
columns correspond to what you want as the (1,1), (1, 2), (2, 1) and (2, 2)
elements, respectively, of the matrix/table to be used for the Fisher test;
* Operate row-wise on the constructed matr
Hi,
I would recommend reformatting the data as a 2x2x1000 array and using apply.

Hello
I have 4 1000*1000 matrix A,B,C,D. I want to use the corresponding element of
the 4 matrices. Using the "for loop" as follow:
E<-o
for (i in 1:1000)
{for (j in 1:1000)
{
E<-fisher.test(matrix(c(A[i][j],B[i][j],C[i][j],D[i][j]),2))#call
fisher.test for every element
}
}
