A couple of weeks ago I wrote a blog post about slopegraphs. There was some polite interest and it was a good chance to practice my functional programming skills so I decided to see if I could make a decent R function from what I had learned. It’s in pretty good shape so I just pushed an update to CRAN (it will take awhile to process). You can also get the latest version from GitHub.
The package also includes other 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.
Plot2WayANOVAwhich as the name implies conducts a 2 way ANOVA and plots the results using
PlotXTabswhich as the name implies plots cross tabulated variables using
newetawhich is a helper function that appends the results of a Type II eta squared calculation onto a classic ANOVA table
Modewhich finds the modal value in a vector of data
SeeDistwhich wraps around ggplot2 to provide visualizations of univariate data.
OurConfis a simulation function that helps you learn about confidence intervals
# Install from CRAN install.packages("CGPfunctions") # Or the development version from GitHub # install.packages("devtools") devtools::install_github("ibecav/CGPfunctions")
