The goal of prener is to document functions that I use frequently in my own research and teaching.
prener is not available from CRAN (and likely never will be!). You can install prener from Github with devtools:
# install.packages("devtools")
devtools::install_github("chris-prener/prener")prener includes a number of functions that I use in conjunction with ggplot2, including a function (cp_points()) for converting measurements from points to inches, centimeters, and millimeters and a function (cp_plotSave()) for standardized export options.
The package also includes a theme specification for ggplot2 that is designed to produce clean, minimal plots and maps for lectures and presentations. The theme is built on top of ggthemes and can be used with a number of backgrounds. Both plots and maps can be produced with a white and a transparent background, and plots can also be produced using a particular shade of gray (#EBEBEB) that I use in the background of my slides.
Finally, the package contains cp_breaks() for calculating breaks in mapping. It is a wrapper around the classInt package's classIntervals function along with cut for calculating factor variables containing breaks for mapping. The various approaches to calculating breaks are summarized in the classInt documentation.
prener includes a helper function for calculating p-values under the t-distribution:
> cp_probt(3.6308, df = 72)
