In SSRA: Sakai Sequential Relation Analysis

Sequential Relation Table

Description

This function builds a table for the tssa and ssra object used to create a treegram

Usage

seqtable(object, order = c("no", "decreasing", "increasing"), digits = 3,
  output = TRUE)

Arguments

object	requires the return object from the TSSA or SSRA function
order	sort by item mean of j?
digits	integer indicating the number of decimal places to be used
output	print result table?
