#' @title Format LTR prediction data to CSV file format
#' @description This function formats the LTR prediction \code{\link{data.frame}}
#' generated by \code{\link{LTRharvest}}, \code{\link{LTRdigest}}, or \code{\link{LTRpred}}
#' to a \code{\link{data.frame}} in \code{CSV} file format.
#' @param LTR.data the LTR prediction \code{\link{data.frame}}
#' generated by \code{\link{LTRharvest}}, \code{\link{LTRdigest}}, or \code{\link{LTRpred}}.
#' @param output filename of the output CSV file.
