Description

This function takes the output from a the mob.data.array or mob.data.array.route.level functions and calculates the sample size of unique observations of the variable along the last dimension of the array (e.g. columns of a 2D matrix or the third dimension in a 3D array)

Usage

calc.samp.size(x)

Arguments

x	a three dimensional array produced by the mob.data.array.route.level function

Value

a named array, matrix, or vector of sample sizes
