\arguments{
\item{x}{A (labelled) data frame, imported by \code{\link[sjlabelled]{read_spss}},
\code{\link[sjlabelled]{read_sas}} or \code{\link[sjlabelled]{read_stata}} function,
or any similar labelled data frame (see \code{\link[sjlabelled]{set_label}}
and \code{\link[sjlabelled]{set_labels}}).}

\item{weight.by}{Name of variable in \code{x} that indicated the vector of
weights that will be applied to weight all  observations. Default is
\code{NULL}, so no weights are used.}

\item{alternate.rows}{Logical, if \code{TRUE}, rows are printed in
alternatig colors (white and light grey by default).}

\item{show.id}{Logical, if \code{TRUE} (default), the variable ID is shown in
the first column.}

\item{show.type}{Logical, if \code{TRUE}, adds information about the
variable type to the variable column.}

\item{show.values}{Logical, if \code{TRUE} (default), the variable values
are shown as additional column.}

\item{show.string.values}{Logical, if \code{TRUE}, elements of character vectors
are also shown. By default, these are omitted due to possibly overlengthy
tables.}

\item{show.labels}{Logical, if \code{TRUE} (default), the value labels are
shown as additional column.}

\item{show.frq}{Logical, if \code{TRUE}, an additional column with
frequencies for each variable is shown.}

\item{show.prc}{Logical, if \code{TRUE}, an additional column with percentage
of frequencies for each variable is shown.}

\item{show.wtd.frq}{Logical, if \code{TRUE}, an additional column with weighted
frequencies for each variable is shown. Weights strem from \code{weight.by}.}

\item{show.wtd.prc}{Logical, if \code{TRUE}, an additional column with weighted
percentage of frequencies for each variable is shown. Weights strem from
\code{weight.by}.}

\item{show.na}{logical, if \code{TRUE}, \code{\link{NA}}'s (missing values)
are added to the output.}

\item{max.len}{Numeric, indicates how many values and value labels per variable
are shown. Useful for variables with many different values, where the output
can be truncated.}

\item{sort.by.name}{Logical, if \code{TRUE}, rows are sorted according to the
variable names. By default, rows (variables) are ordered according to their
order in the data frame.}

\item{wrap.labels}{Numeric, determines how many chars of the value, variable
or axis labels are displayed in one line and when a line break is inserted.}

\item{verbose}{Logical, if \code{TRUE}, a progress bar is displayed
while creating the output.}

\item{CSS}{A \code{\link{list}} with user-defined style-sheet-definitions,
according to the \href{http://www.w3.org/Style/CSS/}{official CSS syntax}.
See 'Details' or \href{https://strengejacke.github.io/sjPlot/articles/table_css.html}{this package-vignette}.}

\item{encoding}{Character vector, indicating the charset encoding used
for variable and value labels. Default is \code{"UTF-8"}. For Windows
Systems, \code{encoding = "Windows-1252"} might be necessary for proper
display of special characters.}

\item{file}{Destination file, if the output should be saved as file.
If \code{NULL} (default), the output will be saved as temporary file and
openend either in the IDE's viewer pane or the default web browser.}

\item{use.viewer}{Logical, if \code{TRUE}, the HTML table is shown in the IDE's
viewer pane. If \code{FALSE} or no viewer available, the HTML table is
opened in a web browser.}

\item{remove.spaces}{Logical, if \code{TRUE}, leading spaces are removed from all lines in the final string
that contains the html-data. Use this, if you want to remove parantheses for html-tags. The html-source
may look less pretty, but it may help when exporting html-tables to office tools.}

\description{
Save (or show) content of an imported SPSS, SAS or Stata data file,
               or any similar labelled \code{data.frame}, as HTML table.
               This quick overview shows variable ID number, name, label,
               type and associated value labels. The result can be
               considered as "codeplan" of the data frame.
