R/getLatestDeaths.R

In jemus42/wurstmineR: Work with a vanilla Minecraft server API

#' Getting death stat
#' 
#' Get the latest deaths from an appropriate API endpoint. 
#' Uses acitvePeople for name substitution.
#' @param url URL of the appropriate API endpoint, defaults to \code{getOption("url.general.deaths.latest")}, 
#' and if that returns \code{NULL}, the Wurstmineberg API endpoint is used.
#' @param people The people dataset to be used for sorting/naming the players, defaults to \code{activePeople}
#' @keywords deaths
#' @return \code{data.frame} containing latest deaths for each player
#' @export
#' @note The API uses a different log than Minecraft stats, tl;dr things are complicated
#' @examples
#' \dontrun{
#' options(url.general.deaths.latest = "http://api.wurstmineberg.de/server/deaths/latest.json")
#' deaths <- getLatestDeaths()
#' }
