Dear list,

I am trying to write a function that will make a matrix of each row of a data frame (4 columns), calculate a fisher.test on each resulting matrix and assign a vector of the p-values. I have gotten through making the matrices, but cannot calculate the fisher.test.

fm<-function(x)

{dfrow<-nrow(x)

mm <- vector("list", dfrow)

for(i in 1:dfrow)

mm[[i]] <- matrix(x[i,],nr=2)

}

I don't know how to access each mm[[i]] as everything I've tried gives me the error that "Error in fisher.test(mm[[i]]) : all entries of x must be nonnegative and finite"

All the numbers in the matrices are between 1 and 600.

Thanks,

Beth
