Percentile

##### Histogram for distribution of a numeric variable

Histogram with statistical details from one-sample test included in the plot as a subtitle.

##### Arguments
data

Dataframe from which variables specified are preferentially to be taken.

x

A numeric variable.

xlab

Label for x axis variable.

title

The text for the plot title.

subtitle

The text for the plot subtitle if you don't want results from one sample test to be displayed.

caption

The text for the plot caption.

type

Type of statistic expected ("parametric" or "nonparametric" or "bayes"). Abbreviations accepted are "p" or "np" or "bf", respectively.

test.value

A number specifying the value of the null hypothesis.

bf.prior

A number between 0.5 and 2 (default 0.707), the prior width to use in calculating Bayes factors.

bf.message

Logical. Decides whether to display Bayes Factor in favor of null hypothesis for parametric test if the null hypothesis can't be rejected (Default: bf.message = TRUE).

k

Number of decimal places expected for results.

results.subtitle

Decides whether the results of statistical tests are to be displayed as subtitle (Default: results.subtitle = TRUE). If set to FALSE, no statistical tests will be run.

centrality.para

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

centrality.colour

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

test.value.line

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

test.value.colour

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

If set to TRUE, you can use it to pick better value with the binwidth argument to stat_bin().

binwidth

The width of the bins. Can be specified as a numeric value, or a function that calculates width from x. The default is to use bins bins that cover the range of the data. You should always override this value, exploring multiple widths to find the best to illustrate the stories in your data.

messages

Decides whether messages references, notes, and warnings are to be displayed (Default: TRUE).
