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 other packages and concepts I’m trying to master. Currently contains:

  • Plot2WayANOVA which as the name implies conducts a 2 way ANOVA and plots the results using ggplot2
  • PlotXTabs which as the name implies plots cross tabulated variables 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
  • Mode which finds the modal value(s) in a vector of data
  • SeeDist which wraps around ggplot2 to provide visualizations of univariate data.
  • OurConf is a simulation function that helps you learn about confidence intervals
