Value

Invisibly returns

the web page style sheet (page.style),
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.

Arguments

var.row: Variable that should be displayed in the table rows.
var.col: Cariable that should be displayed in the table columns.
weight.by: Vector of weights that will be applied to weight all cases. Must be a vector of same length as the input vector. Default is NULL, so no weights are used.
title: String, will be used as table caption.
var.labels: Character vector with variable names, which will be used to label variables in the output.
value.labels: Character vector (or list of character vectors) with value labels of the supplied variables, which will be used to label variable values in the output.
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.
show.obs: Logical, if TRUE, observed values are shown
show.cell.prc: Logical, if TRUE, cell percentage values are shown
show.row.prc: Logical, if TRUE, row percentage values are shown
show.col.prc: Logical, if TRUE, column percentage values are shown
show.exp: Logical, if TRUE, expected values are also shown
show.legend: logical, if TRUE, and depending on plot type and function, a legend is added to the plot.
show.na: logical, if TRUE, NA's (missing values) are added to the output.
show.summary: Logical, if TRUE, a summary row with chi-squared statistics, degrees of freedom and Cramer's V or Phi coefficient and p-value for the chi-squared statistics.
drop.empty: Logical, if TRUE and the variable's values are labeled, values that have no observations are still printed in the table (with frequency 0). If FALSE, values / factor levels with no occurrence in the data are omitted from the output.
statistics: Name of measure of association that should be computed. May be one of "auto", "cramer", "phi", "spearman", "kendall", "pearson" or "fisher". See xtab_statistics.
string.total: Character label for the total column / row header
digits: Amount of decimals for estimates
tdcol.n: Color for highlighting count (observed) values in table cells. Default is black.
tdcol.expected: Color for highlighting expected values in table cells. Default is cyan.
tdcol.cell: Color for highlighting cell percentage values in table cells. Default is red.
tdcol.row: Color for highlighting row percentage values in table cells. Default is blue.
tdcol.col: Color for highlighting column percentage values in table cells. Default is green.
emph.total: Logical, if TRUE, the total column and row will be emphasized with a different background color. See emph.color.
emph.color: Logical, if emph.total = TRUE, this color value will be used for painting the background of the total column and row. Default is a light grey.
prc.sign: The percentage sign that is printed in the table cells, in HTML-format. Default is " %", hence the percentage sign has a non-breaking-space after the percentage value.
hundret: Default value that indicates the 100-percent column-sums (since rounding values may lead to non-exact results). Default is "100.0".
CSS: A list with user-defined style-sheet-definitions, according to the official CSS syntax. See 'Details' or this package-vignette.
encoding: String, indicating the charset encoding used for variable and value labels. Default is NULL, so encoding will be auto-detected depending on your platform (e.g., "UTF-8" for Unix and "Windows-1252" for Windows OS). Change encoding if specific chars are not properly displayed (e.g. German umlauts).
file: Destination file, if the output should be saved as file. If NULL (default), the output will be saved as temporary file and opened either in the IDE's viewer pane or the default web browser.
use.viewer: 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.
remove.spaces: 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.
...: Other arguments, currently passed down to the test statistics functions chisq.test() or fisher.test().

Examples

Run this code

# prepare sample data set
data(efc)

# print simple cross table with labels
if (FALSE) {
if (interactive()) {
  tab_xtab(efc$e16sex, efc$e42dep)

  # print cross table with manually set
  # labels and expected values
  tab_xtab(
    efc$e16sex,
    efc$e42dep,
    var.labels = c("Elder's gender", "Elder's dependency"),
    show.exp = TRUE
  )

  # print minimal cross table with labels, total col/row highlighted
  tab_xtab(efc$e16sex, efc$e42dep, show.cell.prc = FALSE, emph.total = TRUE)

  # User defined style sheet
  tab_xtab(efc$e16sex, efc$e42dep,
           CSS = list(css.table = "border: 2px solid;",
                      css.tdata = "border: 1px solid;",
                      css.horline = "border-bottom: double blue;"))

  # ordinal data, use Kendall's tau
  tab_xtab(efc$e42dep, efc$quol_5, statistics = "kendall")

  # calculate Spearman's rho, with continuity correction
  tab_xtab(
    efc$e42dep,
    efc$quol_5,
    statistics = "spearman",
    exact = FALSE,
    continuity = TRUE
  )
}
