#' Florida motor vehicle crash data 2012 - 2021
#'
#' A dataset containing motorcycle and moped crashes in Florida cities. The data was from
#' two sources: the Florida Department of Transportation (FDOT) and the U.S. Census Bureau.
#' This file shows crash locations for Long-Form-reported crashes within the state of Florida and
#' is subset to those occurring within towns and having a county-city code assigned.
#'

#' \item{crash_date}{date of crash as date}
#' \item{crash_time}{four character string for time on 12 hour interval}
#' \item{date}{date formatted as "YYYY-mm-dd"}
#' \item{dayoweek}{three letter abbreviation for day of week (Mon through Sun)}
#' \item{dot_cnty_cd}{Florida Department of Transportation county code}

#' @note
#'
#' The original dataframe included 158 variables.  A code sheet, while available online,
#' did not match column names or responses.  A variable like "ALCINVCD" presumably was
#' an abbreviation for "alcohol involved" but it was omitted because no explanation
#' could be found.  Additionally, pertinent information on "helmet use" is collected
#' on the uniform long form traffic crash report but could not be found in the variable
#' names.
