Arguments

cell

Vector giving the cell, e.g. c(1, 1, 2) in 3-way table.

dim

Vector giving array dimension, eg c(2, 2, 2).

entry

An entry in an array (a number indexing a vector).

slice_marg

Vector giving the margin of a table, eg. c(2, 3)

slice_cell

Vector giving the corresponding cell of marginal table, e.g. c(1, 2)

perm

Vector giving permutaion of array, eg. c(1, 3, 2).
