Stringendo - A string parsing library

String parsing functionalites for generating plotnames, filenames and path. Used by Stringendo and ggExpress. Complements the new CodeAndRoll2. Many functionalities were part of the formerly used CodeAndRoll (v1).

Installation

Install directly from GitHub via devtools with one R command:

# install.packages("devtools"); # If you don't have it.
require("devtools")
devtools::install_github(repo = "vertesy/Stringendo")

…then simply load the package:

require("Stringendo")

Alternatively, you simply source it from the web. This way function help will not work, and you will have no local copy of the code on your hard drive.
