##' Using the classical F test statistic for a balanced one-way design, this function computes the corresponding Bayes factor test.
##'
##' For F statistics computed from balanced one-way designs, this function can
##' be used to compute the Bayes factor testing the model that all group means
##' are not equal to the grand mean, versus the null model that all group means
##' are equal. It can be used when you don't have access to the full data set
##' for analysis by \code{\link{lmBF}}, but you do have the test statistic.
##'
##' For details about the model, see the help for \code{\link{anovaBF}}, and the references therein.
##'
##' The Bayes factor is computed via Gaussian quadrature.
##' @title Use F statistic to compute Bayes factor for balanced one-way designs
##' @param F F statistic from classical ANOVA
##' @param N number of observations per cell or group
##' @param J number of cells or groups
##' @param rscale numeric prior scale
##' @param simple if \code{TRUE}, return only the Bayes factor
##' @return If \code{simple} is \code{TRUE}, returns the Bayes factor (against the
##' intercept-only null). If \code{FALSE}, the function returns a
##' vector of length 3 containing the computed log(e) Bayes factor,
##' along with a proportional error estimate on the Bayes factor and the method used to compute it.
