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
