Overview

A package that includes functions that I find useful for teaching statistics as well as actually practicing the art. They typically are not “new” methods but rather wrappers around either base R or tidyverse packages. Currently contains the following major user oriented functions:

• Plot2WayANOVA which as the name implies conducts a 2 way ANOVA and plots the results using ggplot2
• PlotXTabs2 which wraps around ggplot2 to provide Bivariate bar charts for categorical and ordinal data.
• newggslopegraph which creates a Tufte“esque” slopegraph using ggplot2
• chaid_table provides tabular summary of CHAID partykit object
• cross2_var_vectors a helper function to build lists of “crossed” variables
• SeeDist which wraps around ggplot2 to provide visualizations of univariate data.
• OurConf is a simulation function that helps you learn about confidence intervals
