Powell Miscellaneous Functions for Teaching and Learning Statistics.
Description
Miscellaneous functions 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.

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 usingggplot2
PlotXTabs2
which wraps aroundggplot2
to provide Bivariate bar charts for categorical and ordinal data.newggslopegraph
which creates a Tufte“esque” slopegraph usingggplot2
chaid_table
provides tabular summary ofCHAID
partykit
objectcross2_var_vectors
a helper function to build lists of “crossed” variablesSeeDist
which wraps aroundggplot2
to provide visualizations of univariate data.OurConf
is a simulation function that helps you learn about confidence intervals
