R/summary.direct.evidence.plot.R

In MathiasHarrer/dmetar: Companion R Package for the Guide 'Doing Meta-Analysis in R'

#' Print, summary and plot methods for objects created using 'dmetar' functions
#'
#' Print, summary and plot S3 methods for objects of class \code{direct.evidence.plot}, \code{find.outliers},
#' \code{influence.analysis}, \code{multimodel.inference}, \code{pcurve}, \code{power.analysis},
#' \code{subgroup.analysis.mixed.effects}, and \code{sucra}.
#'
#'
#' @param object An object of class \code{direct.evidence.plot}.
#' @param ... Additional arguments.
#'
#' @details
#' A total of four package-specific S3 methods are provided in \code{dmetar}: S3 methods for \code{print},
#' \code{summary}, \code{plot} and \code{forest}. Outputs from \code{print} and \code{summary} are always identical.
#' When both \code{plot} and \code{forest} are available for a class, outputs of both functions are identical (i.e., a forest
#' plot is returned). The \code{forest}/\code{plot} function allows additional arguments of the \code{meta.forest} or
#' \code{metafor}'s code{\link[metafor]{forest}} function (depending on the class of the meta-analysis object on which prior
#' calculations are based on). These can be used for further styling of the forest plot.
