rg_remove_outliers: Remove outliers from a vector based on sigma test or...

In sitscholl/Rgadgets: Contains various utility functions developed during the PhD

Description

This function removes outliers from a vector and replaces them with an optional value based on sigma test or the interquartile range

Usage

rg_remove_outliers(
  v,
  type = "iqr",
  fill = NA,
  range = ifelse(type == "iqr", 1.5, 3),
  na.rm = FALSE
)

Arguments

v	numeric vector
type	string, one of iqr for interquartile range or sigma for sigma test
fill	numeric or function, either a fixed value or a function such as mean from which the replacement values can be computed
range	numeric, this number is multiplied with the interquartile range for type = 'iqr' or the standard deviation for type = 'sigma' and determines the width of the window in which values are considered as NOT being outliers
na.rm	logical; if true, any NA and NaN's are removed from v before the quantiles, means or standard deviations are computed.

Examples

remove_outliers(c(1, 2, 3, 100))
