Description

change outlier values as NA or winsorize

replace_outlier(object, method, nSD)
# S3 method for default
replace_outlier(object, method = "winsorize", nSD = 5)
# S3 method for data.frame
replace_outlier(object, method = "winsorize", nSD = 5)
# S3 method for Metabolite
replace_outlier(object, method = "winsorize", nSD = 5)

Arguments

object

An object, a vector, data.frame, data.table or Metabolite.

method
