imputeLOD {rexposome}R Documentation

Function to impute values under limit of detection

Description

Homologous function to the ilod method of ExposomeSet for a given data.frame of exposures and a vector of threshold. The use of this function is related to HELIX Project.

Usage

imputeLOD(x, lod, description = NULL, pNA = 0.2, pLOD = 0, log = TRUE,
  seed = NULL)

Arguments

x

data.frame containing the exposures as columns and the samples as rows.

lod

vectro containing the

description

1 means values under LOD while 2 means quantifiable value, 3

pNA

(default: 0.2) maximum percentage of allowed missing data

pLOD

(default: 0) minimum percentave of values under LOD

log

(default: NA) log transformation to normalize data

seed

(default: NULL)

Value

A new data.frame with the imputed exposures.
