Save (or show) content of an imported SPSS, SAS or Stata data file, or any similar labelled 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.

A (labelled) data frame, imported by read_spss, read_sas or read_stata function, or any similar labelled data frame (see set_label and set_labels).

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


Logical, if TRUE, alternating rows are highlighted with a light gray background color.

Logical, if TRUE (default), the variable ID is shown in the first column.


Logical, if TRUE, adds information about the variable type to the variable column.


Logical, if TRUE (default), the variable values are shown as additional column.


Logical, if TRUE, elements of character vectors are also shown. By default, these are omitted due to possibly overlengthy tables.


Logical, if TRUE (default), the value labels are shown as additional column.


Logical, if TRUE, an additional column with frequencies for each variable is shown.


Logical, if TRUE, an additional column with percentage of frequencies for each variable is shown.


Logical, if TRUE, an additional column with weighted frequencies for each variable is shown. Weights strem from


Logical, if TRUE, an additional column with weighted percentage of frequencies for each variable is shown. Weights strem from

logical, if TRUE, NA's (missing values) are added to the output.


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.

Logical, if TRUE, rows are sorted according to the variable names. By default, rows (variables) are ordered according to their order in the data frame.


numeric, determines how many chars of the value, variable or axis labels are displayed in one line and when a line break is inserted.


logical, if TRUE, the progress bar that is displayed when creating the output is hidden. Default in FALSE, hence the bar is visible.


A list with user-defined style-sheet-definitions, according to the official CSS syntax. For more details, see this package-vignette, or 'Details' in sjt.frq.


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


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


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


Logical, if TRUE, the html-output is neither opened in a browser nor shown in the viewer pane and not even saved to file. This option is useful when the html output should be used in knitr documents. The html output can be accessed via the return value.


Logical, if 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.


Invisibly returns

  • the web page style sheet (,

  • the web page content (page.content),

  • the complete html-output (page.complete) and

  • the html-table with inline-css for use with knitr (knitr)

for further use.
