Martin's function package, where assorted functions I have either written or borrowed from others (primarily the latter) are saved for future use.
To download and install the {marfunpack} package, you will need the {remotes} package:
install.packages("remotes")
remotes::install_github("monkmanmh/marfunpack")
Once you have {marfunpack} installed, load it using the library() function:
library(marfunpack)
Utility function "not in"
