Calculate boxplot values

Description

Calculate boxplot values

Usage

compute_boxplot(x, var = NULL, coef = 1.5)

Arguments

x	Dataset-like object to compute boxplot values. There are built-in methods for data frames, grouped data frames, and ggvis visualisations.
var	Name of variable for which to compute boxplot values. The variable must be continuous.
coef	The maximum length of the whiskers as multiple of the inter-quartile range. Default value is 1.5.

Value

A data frame with columns:

min_	Lower whisker = smallest observation greater than or equal to lower hinge - 1.5 * IQR
lower_	Lower hinge (25th percentile)
median_	Median (50th percentile)
upper_	Upper hinge (75th percentile)
max_	Upper whisker = largest observation less than or equal to upper hinge + 1.5 * IQR
outliers_	A vector of values that are outside of the min and max
