Defines functions plot.InfluenceAnalysis

Documented in plot.InfluenceAnalysis

#' 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 x An object of class \code{influence.analysis}.
#' @param which Which plot(s) should be generated? Can be either \code{"all"} (default), \code{"baujat"}, \code{"influence"},
#' \code{"ES"} (forest plot sorted by effect size) or \code{"I2"} (forest plot sorted by heterogeneity).
#' @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.
