Load packages
library(tidyverse)Where does my function reside?
Finding the package of a given R function is some hassle. I am not aware of a quick built-in way in R to find the package of a function.
That’s why I came up with my own function, check it out:
Install package
Speaking of packages of function, that’s the package where this function stays:
library(devtools)
install_github("sebastiansauer/prada")Example
