tomogRxC: Plotting Ecological Inference Estimates with eiRxC information

Description

A tomography plot for an estimated Ecological Inference model in RxC data.

Usage

tomogRxC(formula, data, total=NULL, refine=100)

Arguments

formula

A formula of the form cbind(col1, col2,...)~cbind(row1,row2,...)

data

data that contains the data that corresponds to the formula

total

`total' is the name of the variable in the dataset that contains the number of individuals in each unit

refine

specifies the amount of refinement for the image. Higher numbers mean better resolution.
