Arguments

data

A dataframe (or a tibble) from which variables specified are to be taken. A matrix or tables will not be accepted.

x

A numeric variable.

y

Label or grouping variable.

xlab

Labels for x and y axis variables. If NULL (default), variable names for x and y will be used.

ylab

Label for y axis variable (Default: "term").

title

The text for the plot title.

stat.title

A character describing the test being run, which will be added as a prefix in the subtitle. The default is NULL. An example of a stat.title argument will be something like "Student's t-test: ".

subtitle

The text for the plot subtitle. Will work only if results.subtitle = FALSE.

caption

The text for the plot caption.

type

Type of statistic expected ("parametric" or "nonparametric" or "robust" or "bayes").Corresponding abbreviations are also accepted: "p" (for parametric), "np" (nonparametric), "r" (robust), or "bf"resp.

test.value

A number specifying the value of the null hypothesis (Default: 0).

bf.prior

A numeric value between 0.5 and 2 (default 0.707), the prior width to use in calculating Bayes Factors.

bf.message

Logical that decides whether to display Bayes Factor in favor of the null hypothesis. This argument is relevant only for parametric test (Default: TRUE).

robust.estimator

If type = "robust", a robust estimator to be used ("onestep" (Default), "mom", or "median"). For more, see ?WRS2::onesampb.

effsize.type

Type of effect size needed for parametric tests. The argument can be "biased" ("d" for Cohen's d) or "unbiased" ("g" Hedge's g for t-test). The default is "g".

effsize.noncentral

Logical indicating whether to use non-central t-distributions for computing the confidence interval for Cohen's d or Hedge's g (Default: TRUE).

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).

k

Number of digits after decimal point (should be an integer) (Default: k = 2).

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.

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.

point.color

Character describing color for the point (Default: "black").

point.size

Numeric specifying size for the point (Default: 3).

point.shape

Numeric specifying shape to draw the points (Default: 16 (a dot)).

centrality.para

Decides which measure of central tendency ("mean" or "median") is to be displayed as a vertical line.

centrality.color

Decides color for the vertical line for centrality parameter (Default: "blue").

centrality.size

Decides size for the vertical line for centrality parameter (Default: 1.2).

centrality.linetype

Decides linetype for the vertical line for centrality parameter (Default: "dashed").

centrality.line.labeller

A logical that decides whether line labels should be displayed for the centrality.para line (Default: TRUE).

centrality.k

Integer denoting the number of decimal places expected for centrality parameter label. (Default: 2).

test.value.line

Decides whether test value is to be displayed as a vertical line (Default: FALSE).

test.value.color

Decides color for the vertical line denoting test value (Default: "black").

test.value.size

Decides size for the vertical line for test value (Default: 1.2).

test.value.linetype

Decides linetype for the vertical line for test value (Default: "dashed").

test.line.labeller

A logical that decides whether line labels should be displayed for test.value line (Default: TRUE).

test.k

Integer denoting the number of decimal places expected for test.value label. (Default: 0 ).

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).
