#' print.summarytools
#'
#' Display \code{summarytools} objects in the console, in Web Browser or in
#' \emph{RStudio}'s Viewer, or write content to file.
#'
#' @usage
#' \method{print}{summarytools}(x, method = "pander", file = "",
#' append = FALSE, report.title = NA, table.classes = NA,
#' bootstrap.css = st_options('bootstrap.css'),
#' custom.css = st_options('custom.css'), silent = FALSE,
#' footnote = st_options('footnote'), max.tbl.height = Inf,
#' collapse = 0, escape.pipe = st_options("escape.pipe"), \dots)
#'
#' @param x A \emph{summarytools} object, created by one of the four core
#' functions (\code{\link{freq}}, \code{\link{descr}}, \code{\link{ctable}},
#' or \code{\link{dfSummary}}).
#' @param method Character. One of \dQuote{pander}, \dQuote{viewer},
#' \dQuote{browser}, or \dQuote{render}. Default value for the \code{print()}
#' method is \dQuote{pander}; for \code{view()}/\code{stview()}, default is
#' \dQuote{viewer} if session is running in \emph{RStudio}, \dQuote{browser}
#' otherwise. The main use for \dQuote{render} is in \emph{R Markdown}
#' documents.
#' @param file Character. File name to write output to. Defaults to \dQuote{}.
#' @param append Logical. Append output to existing file (specified using the
#' \emph{file} argument). \code{FALSE} by default.
#' @param report.title Character. For \emph{html} reports, this goes into the
#' \code{<title>} tag. When left to \code{NA} (default), the first line of the
#' heading section is used (\emph{e.g.}: \dQuote{Data Frame Summary}).
#' @param table.classes Character. Additional \emph{html} classes to assign to
#' output tables. \emph{Bootstrap css} classes can be used. User-defined
#' classes (see the \emph{custom.css} argument) are also specified here. See
#' \emph{details} section. \code{NA} by default.
#' @param bootstrap.css Logical. When generating an \emph{html} document,
#' include the \dQuote{\emph{includes/stylesheets/bootstrap.min.css"}} file
#' content inside a \code{<style type="text/css">} tag in the document's
#' \code{<head>}. \code{TRUE} by default. Can be set globally with
#' \code{\link{st_options}}.
#' @param custom.css Character. Path to a custom \emph{.css} file. Classes
#' defined in this must also appear in the \code{table.classes} parameter
#' in order to be applied to the table(s). Can be set globally with
#' \code{\link{st_options}}. \code{NA} by default.
#' @param silent Logical. Set to \code{TRUE} to hide console messages
#' (\emph{e.g.}: ignored variables or \code{NaN} to \code{NA}
#' transformations). \code{FALSE} by default.
#' @param footnote Character. Text to display just after \emph{html} output
#' tables. The default value (\dQuote{\emph{default}}) produces a two-line
#' footnote indicating the package's name and version, the R version, and
#' the current date. Has no effect on \emph{ascii} or \emph{markdown}
#' content. Can contain standard \emph{html} tags. Set to \code{NA} to omit.
#' Can be set globally with \code{\link{st_options}}.
#' @param max.tbl.height Numeric. Maximum table height \emph{in pixels} allowed
#' in rendered \code{dfSummary()} tables. When this argument is used, results
#' will show up in a \code{<div>} with the specified height and a scroll bar.
#' Intended to be used in \emph{Rmd} documents with \code{method = "render"}.
#' \code{Inf} by default.
#' @param collapse Numeric. \code{0} by default. Set to \code{1} to make
#' \code{freq()} sections collapsible (when clicking on the variable name).
#' Future versions might provide alternate collapsing options.
#' @param escape.pipe Logical. Set to \code{TRUE} when \code{style="grid"}
#' and \code{file} argument is supplied if the intent is to generate a text
#' file that can be converted to other formats using \emph{Pandoc}. Can be
#' set globally with \code{\link{st_options}}.
#' @param \dots Additional arguments used to override attributes stored in the
#' object, or to change formatting via \code{\link[base]{format}} or
#' \code{\link[pander]{pander}}. See \emph{Details}.
#'
#' @return \code{NULL} when \code{method="pander"}; A file path returned
#' invisibly when \code{method="viewer"} or \code{"browser"}. In the
#' latter case, the file path is also passed to \code{shell.exec}
#' (\emph{Windows}) or \code{\link{system}} (\emph{*nix}), causing
#' the document to be opened in default Web browser.
#'
#' @details
#' \code{Ascii} and \emph{markdown} tables are generated using
#' \code{\link[pander]{pander}}.
#'
#' The following arguments can be used to override formatting attributes stored
#' in the object:
#' \itemize{
#' \item \code{style}
#' \item \code{round.digits} (except for \emph{dfSummary} objects)
#' \item \code{plain.ascii}
#' \item \code{justify}
#' \item \code{split.tables}
#' \item \code{headings}
#' \item \code{display.labels}

#' \item \code{graph.col} (\code{\link{dfSummary}} objects only)
#' \item \code{valid.col} (\code{\link{dfSummary}} objects only)
#' \item \code{na.col} (\code{\link{dfSummary}} objects only)
#' \item \code{col.widths} (\code{\link{dfSummary}} objects only)
#' \item \code{keep.grp.vars} (\code{\link{dfSummary}} objects only)
#' \item \code{report.nas} (\code{\link{freq}} objects only)
#' \item \code{display.type} (\code{\link{freq}} objects only)
#' \item \code{missing} (\code{\link{freq}} objects only)
#' \item \code{totals} (\code{\link{freq}} and \code{\link{ctable}} objects)
#' \item \code{caption} (\code{\link{freq}} and \code{\link{ctable}} objects)
#' }
#'
#' The following arguments can be used to override heading elements:
#'
#' \itemize{
#' \item \code{Data.frame}
#' \item \code{Data.frame.label}
#' \item \code{Variable}
#' \item \code{Variable.label}
#' \item \code{Group}
#' \item \code{date}
#' \item \code{Weights} (\code{\link{freq}} & \code{\link{descr}} objects)
#' \item \code{Data.type} (\code{\link{freq}} objects only)
#' \item \code{Row.variable} (\code{\link{ctable}} objects only)
#' \item \code{Col.variable} (\code{\link{ctable}} objects only)

Documented in print.summarytools
#' print.summarytools
#'
#' Display \code{summarytools} objects in the console, in Web Browser or in
#' \emph{RStudio}'s Viewer, or write content to file.
#'
#' @usage
#' \method{print}{summarytools}(x, method = "pander", file = "",
#' append = FALSE, report.title = NA, table.classes = NA,
#' bootstrap.css = st_options('bootstrap.css'),
#' custom.css = st_options('custom.css'), silent = FALSE,
#' footnote = st_options('footnote'), max.tbl.height = Inf,
#' collapse = 0, escape.pipe = st_options("escape.pipe"), \dots)
#'
#' @param x A \emph{summarytools} object, created by one of the four core
#' functions (\code{\link{freq}}, \code{\link{descr}}, \code{\link{ctable}},
#' or \code{\link{dfSummary}}).
#' @param method Character. One of \dQuote{pander}, \dQuote{viewer},
#' \dQuote{browser}, or \dQuote{render}. Default value for the \code{print()}
#' method is \dQuote{pander}; for \code{view()}/\code{stview()}, default is
#' \dQuote{viewer} if session is running in \emph{RStudio}, \dQuote{browser}
#' otherwise. The main use for \dQuote{render} is in \emph{R Markdown}
#' documents.
#' @param file Character. File name to write output to. Defaults to \dQuote{}.
#' @param append Logical. Append output to existing file (specified using the
#' \emph{file} argument). \code{FALSE} by default.
#' @param report.title Character. For \emph{html} reports, this goes into the
#' \code{<title>} tag. When left to \code{NA} (default), the first line of the
#' heading section is used (\emph{e.g.}: \dQuote{Data Frame Summary}).
#' @param table.classes Character. Additional \emph{html} classes to assign to
#' output tables. \emph{Bootstrap css} classes can be used. User-defined
#' classes (see the \emph{custom.css} argument) are also specified here. See
#' \emph{details} section. \code{NA} by default.
#' @param bootstrap.css Logical. When generating an \emph{html} document,
#' include the \dQuote{\emph{includes/stylesheets/bootstrap.min.css"}} file
#' content inside a \code{<style type="text/css">} tag in the document's
#' \code{<head>}. \code{TRUE} by default. Can be set globally with
#' \code{\link{st_options}}.
#' @param custom.css Character. Path to a custom \emph{.css} file. Classes
#' defined in this must also appear in the \code{table.classes} parameter
#' in order to be applied to the table(s). Can be set globally with
#' \code{\link{st_options}}. \code{NA} by default.
#' @param silent Logical. Set to \code{TRUE} to hide console messages
#' (\emph{e.g.}: ignored variables or \code{NaN} to \code{NA}
#' transformations). \code{FALSE} by default.
#' @param footnote Character. Text to display just after \emph{html} output
#' tables. The default value (\dQuote{\emph{default}}) produces a two-line
#' footnote indicating the package's name and version, the R version, and
#' the current date. Has no effect on \emph{ascii} or \emph{markdown}
#' content. Can contain standard \emph{html} tags. Set to \code{NA} to omit.
#' Can be set globally with \code{\link{st_options}}.
#' @param max.tbl.height Numeric. Maximum table height \emph{in pixels} allowed
#' in rendered \code{dfSummary()} tables. When this argument is used, results
#' will show up in a \code{<div>} with the specified height and a scroll bar.
#' Intended to be used in \emph{Rmd} documents with \code{method = "render"}.
#' \code{Inf} by default.
#' @param collapse Numeric. \code{0} by default. Set to \code{1} to make
#' \code{freq()} sections collapsible (when clicking on the variable name).
#' Future versions might provide alternate collapsing options.
#' @param escape.pipe Logical. Set to \code{TRUE} when \code{style="grid"}
#' and \code{file} argument is supplied if the intent is to generate a text
#' file that can be converted to other formats using \emph{Pandoc}. Can be
#' set globally with \code{\link{st_options}}.
#' @param \dots Additional arguments used to override attributes stored in the
#' object, or to change formatting via \code{\link[base]{format}} or
#' \code{\link[pander]{pander}}. See \emph{Details}.
#'
#' @return \code{NULL} when \code{method="pander"}; A file path returned
#' invisibly when \code{method="viewer"} or \code{"browser"}. In the
#' latter case, the file path is also passed to \code{shell.exec}
#' (\emph{Windows}) or \code{\link{system}} (\emph{*nix}), causing
#' the document to be opened in default Web browser.
#'
#' @details
#' \code{Ascii} and \emph{markdown} tables are generated using
#' \code{\link[pander]{pander}}.
#'
#' The following arguments can be used to override formatting attributes stored
#' in the object:
#' \itemize{
#' \item \code{style}
#' \item \code{round.digits} (except for \emph{dfSummary} objects)
#' \item \code{plain.ascii}
#' \item \code{justify}

#' \item \code{display.type} (\code{\link{freq}} objects only)
#' \item \code{missing} (\code{\link{freq}} objects only)
#' \item \code{totals} (\code{\link{freq}} and \code{\link{ctable}} objects)
#' \item \code{caption} (\code{\link{freq}} and \code{\link{ctable}} objects)
#' }
#'
#' The following arguments can be used to override heading elements:
#'
#' \itemize{
#' \item \code{Data.frame}
#' \item \code{Data.frame.label}
#' \item \code{Variable}
#' \item \code{Variable.label}
