CRAN Version Build Status Downloads

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
  • newggslopegraph which creates a Tufte“esque” slopegraph using ggplot2
  • 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

Installation

# Install from CRAN
install.packages("CGPfunctions")

# Or the development version from GitHub
# install.packages("devtools")
devtools::install_github("ibecav/CGPfunctions")
