#' @title Turn ate Object Into a \code{data.table}
#' @description Turn ate object into a \code{data.table}.
#' @name as.data.table.ate

#' @param x object obtained with function \code{ate}
#' @param keep.rownames Not used.
#' @param estimator [character] The type of estimator relative to which the estimates should be output.
#' @param type [character vector] The type of risk to export.
#' Can be \code{"meanRisk"} to export the risks specific to each treatment group,
#' \code{"diffRisk"} to export the difference in risks between treatment groups,
#' or \code{"ratioRisk"} to export the ratio of risks between treatment groups.
#' @param ... Not used.
