expand.table: Expand summary table of patterns and frequencies

In xzhaopsy/MIRT: Multidimensional Item Response Theory

Description

The expand.table function expands a summary table of unique response patterns to a full sized data-set. The response frequencies must be on the rightmost column of the input data.

Usage

expand.table(tabdata, sample = FALSE)

Arguments

tabdata	An object of class data.frame or matrix with the unique response patterns and the number of frequencies in the rightmost column
sample	logical; randomly switch the rows in the expanded table? This does not change the expanded data, only the row locations

Value

Returns a numeric matrix with all the response patterns.
