IPV: IPV: A package to create Item Pool Visualizations

Description Input Functions Chart Functions Workflow


The IPV package provides two categories of important functions: input, and chart.

Input Functions

The input functions help preprocessing your data, so the other functions can use them. input_manual_simple input_manual_nested input_manual_process input_excel

Chart Functions

Chart functions create a ggplot2 object (the chart) and optionally save this object to a file. There are three types of charts. item_chart facet_chart nested_chart


Prepare your data using input functions or by hand. Choose a chart type and use the proper chart function. Then

  1. choose parameter values of the chart function

  2. check chart appearance

  3. repeat until satisfied
