In ccebra/Divvy-Data: Data package of Divvy bike ridership in Chicago

#' Divvy data cleaned and formatted to include station usage statistics per
#' month since the start of the program, in terms of the number of rides, and
#' rides by classic or electric bike. Note that, due to data parsing, both
#' departing from, and arriving from, a station count as a station usage, so
#' all rides are counted twice.
#'
#' This package contains files corresponding to each month that the Divvy bike
#' program has been open.
