Flag Tukey (IQR) outliers in a numeric vector

Values below Q1 - kIQR or above Q3 + kIQR. This is the symmetric boxplot rule; a skew-aware (medcouple) variant can be added later.

Usage

data_check_outliers(x, k = 1.5, n_max = 10)

Arguments

x

a numeric vector

k

IQR multiplier (default 1.5)

n_max

max number of flagged values to list in the message

Value

list(problem, message, values, lower, upper)

Examples

data_check_outliers(c(10, 11, 9, 12, 10, 95))$message
#> [1] "1 outlier value outside [7.38, 14.4]: 95"
