Description

change outlier values as NA or winsorize

Usage

replace_outlier(object, method, nSD)

## Default S3 method:
replace_outlier(object, method = "winsorize", nSD = 5)

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

## S3 method for class 'Metabolite'
replace_outlier(object, method = "winsorize", nSD = 5)

Arguments

object	An object, a vector, data.frame, data.table or Metabolite.
method	Replace outlier value method, the default method is 'winsorize': replace the outlier values by the maximum and/or minimum values of the remaining values. 'as_NA': set as NA (do not use this method if using half-min imputation).
nSD	Define the N times of the SD as outliers.
