#' Rhipicephalus microplus occurrence and background environment data
#'
#' Example dataset for *Rhipicephalus microplus* (cattle tick) presence points
#' and a random background sample inside the accessible area (M).
#'
#' @format A list with four data frames:
#' \describe{
#'   \item{coords_occ}{Geographic coordinates (lon, lat) of presence points.}
#'   \item{env_occ}{Environmental values of bio1 and rh at presence points.}
#'   \item{coords_m}{Geographic coordinates (lon, lat) of background points in M.}
#'   \item{env_m}{Environmental values of bio1 and rh at background points.}
#' }
#' @source Occurrence and background data prepared from the Garrapatas dataset;
#' raster layers are annual mean temperature (bio1, in °C) and relative
#' humidity (rh, in percent).
