# WORKS ========================================================================================

# roxygen2::roxygenise()
#
# To learn the documenation workflow see: https://cran.r-project.org/web/packages/roxygen2/vignettes/rd.html
#
# For learning how to generate Rd files with roxygen see this introduction by Hadley Wickham:
# https://cran.r-project.org/web/packages/roxygen2/vignettes/rd.html
#
# Requires: R files in R folder, man folder must exist,
# DESCRIPTION file must exist (generate with devtools::create_description())
# devtools::create_description()
#
# Generates Rd files and creates or overwrites the NAMESPACE file using the @export tags!
