missingval_result: Creates an object of class naRes (NA Result)

In pmartR/pmartR: Panomics Marketplace - Quality Control and Statistical Analysis for Panomics Data

Creates an object of class naRes (NA Result)

Description

This function takes in an omicsData object, and outputs a list of two data frames, one containing the number of missing values by sample, and the other containing the number of missing values by molecule

Usage

missingval_result(omicsData)

Arguments

omicsData

an object of class "pepData", "proData", "metabData", "lipidData", "nmrData", or "seqData", created by as.pepData, as.proData, as.metabData, as.lipidData, as.nmrData, or as.seqData, respectively.

Value

S3 object of class naRes, which is a list of two data frames, one containing the number of missing values per sample, and the other containing the number of missing values per molecule. For count data, zeroes represent missing values; for abundance data, NA's represent missing values. This object can be used with 'plot' and 'summary' methods to examine the missing values in the dataset.

Examples

library(pmartRdata)
result1 = missingval_result(omicsData = lipid_neg_object)
result2 = missingval_result(omicsData = metab_object)
