Generation of non-parametric bootstrap samples
Description
This function allows to generate non-parametric bootstrap samples in order to check the
optimal dimension number of three-way correspondence analysis. The boostrap samples
have the same marginal proportions and the total number of the original table.
Do nboots bootstrap on the indicator matrix X (observations x (rows+cols+tubs) categories).
From a three-way contingency table, it makes the indicator using makeindicator
.
The output is a list of three-way tables.
Usage

Arguments
