Arguments
data
A dataframe (or a tibble) from which variables specified are to be taken. A matrix or tables will not be accepted.
main
The variable to use as the rows in the contingency table.
condition
The variable to use as the columns in the contingency table. Default is NULL. If NULL, one-sample proportion test (a goodness of fit test) will be run for the x variable. Otherwise an appropriate association test will be run. This argument can not be NULL for ggbarstats function.
counts
A string naming a variable in data containing counts, or NULL if each row represents a single observation (Default).
ratio
A vector of proportions: the expected proportions for the proportion test (should sum to 1). Default is NULL, which means the null is equal theoretical proportions across the levels of the nominal variable. This means if there are two levels this will be ratio = c(0.5,0.5) or if there are four levels this will be ratio = c(0.25,0.25,0.25,0.25), etc.
paired
Logical indicating whether data came from a within-subjects or repeated measures design study (Default: FALSE). If TRUE, McNemar's test subtitle will be returned. If FALSE, Pearson's chi-square test will be returned.
labels.legend
A character vector with custom labels for levels of the x variable displayed in the legend.
results.subtitle
Decides whether the results of statistical tests are to be displayed as a subtitle (Default: TRUE). If set to FALSE, only the plot will be returned.
stat.title
Title for the effect being investigated with the chi-square test. The default is NULL, i.e. no title will be added to describe the effect being shown. An example of a stat.title argument will be something like "main x condition" or "interaction".
sample.size.label
Logical that decides whether sample size information should be displayed for each level of the grouping variable y (Default: TRUE).
label.separator
If "both" counts and proportion information is to be displayed in a label, this argument decides whether these two pieces of information are going to be on the same line (" ") or on separate lines ("\n").
label.text.size
Numeric that decides text size for slice/bar labels (Default: 4).
label.fill.color
Character that specifies fill color for slice/bar labels (Default: white).
label.fill.alpha
Numeric that specifies fill color transparency or "alpha" for slice/bar labels (Default: 1 range 0 to 1).
bar.outline.color
Character specifying color for bars (default: "black").
bf.message
Logical that decides whether to display a caption with results from Bayes Factor test in favor of the null hypothesis (default: FALSE).
sampling.plan
Character describing the sampling plan. Possible options are "indepMulti" (independent multinomial; default), "poisson", "jointMulti" (joint multinomial), "hypergeom" (hypergeometric). For more, see ?BayesFactor::contingencyTableBF().
fixed.margin
For the independent multinomial sampling plan, which margin is fixed ("rows" or "cols"). Defaults to "rows".
prior.concentration
Specifies the prior concentration parameter, set to 1 by default. It indexes the expected deviation from the null hypothesis under the alternative, and corresponds to Gunel and Dickey's (1974) "a" parameter.
title
The text for the plot title.
subtitle
The text for the plot subtitle. Will work only if results.subtitle = FALSE.
caption
The text for the plot caption.
legend.position
The position of the legend "none", "left", "right", "bottom", "top" (Default: "right").
x.axis.orientation
The orientation of the x axis labels one of "slant" or "vertical" to change from the default horizontal orientation (Default: NULL which is horizontal).
conf.level
Scalar between 0 and 1. If unspecified, the defaults return 95% lower and upper confidence intervals (0.95).
nboot
Number of bootstrap samples for computing confidence interval for the effect size (Default: 100).
simulate.p.value
a logical indicating whether to compute p-values by Monte Carlo simulation.
B
an integer specifying the number of replicates used in the Monte Carlo test.
bias.correct
If TRUE, a bias correction will be applied to Cramer's V.
legend.title
Title text for the legend.
xlab
Custom text for the x axis label (Default: NULL, which will cause the x axis label to be the x variable).
ylab
Custom text for the y axis label (Default: "percent").
k
Number of digits after decimal point (should be an integer) (Default: k = 2).
perc.k
Numeric that decides number of decimal places for percentage labels (Default: 0).
bar.label, data.label
Character decides what information needs to be displayed on the label in each pie slice. Possible options are "percentage" (default), "counts", "both".
bar.proptest
Decides whether proportion test for main variable is to be carried out for each level of y (Default: TRUE).
ggtheme
A function, ggplot2 theme name. Default value is ggplot2::theme_bw(). Any of the ggplot2 themes, or themes from extension packages are allowed (e.g., ggthemes::theme_fivethirtyeight(), hrbrthemes::theme_ipsum_ps(), etc.).
ggstatsplot.layer
Logical that decides whether theme_ggstatsplot theme elements are to be displayed along with the selected ggtheme (Default: TRUE). theme_ggstatsplot is an opinionated theme layer that override some aspects of the selected ggtheme.
package
Name of package from which the palette is desired as string or symbol.
palette
Name of palette as string or symbol.
direction
Either 1 or -1. If -1 the palette will be reversed.
ggplot.component
A ggplot component to be added to the plot prepared by ggstatsplot. This argument is primarily helpful for grouped_ variant of the current function. Default is NULL. The argument should be entered as a function. If the given function has an argument axes.range.restrict and if it has been set to TRUE, the added ggplot component might not work as expected.
return
Character that describes what is to be returned: can be "plot" (default) or "subtitle" or "caption". Setting this to "subtitle" will return the expression containing statistical results. If you have set results.subtitle = FALSE, then this will return a NULL. Setting this to "caption" will return the expression containing details about Bayes Factor analysis, but valid only when type = "parametric" and bf.message = TRUE, otherwise this will return a NULL.
messages
Decides whether messages references, notes, and warnings are to be displayed (Default: TRUE).
x
The variable to use as the rows in the contingency table.
y
The variable to use as the columns in the contingency table. Default is NULL. If NULL, one-sample proportion test (a goodness of fit test) will be run for the x variable. Otherwise an appropriate association test will be run. This argument can not be NULL for ggbarstats function.
