compute_boxplot: 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
