SanityCheckData: Sanity Check Data

In xia-lab/MetaboAnalystR: An R Package for Comprehensive Analysis of Metabolomics Data

Sanity Check Data

Description

SanityCheckData is used for data processing, and performs a basic sanity check of the uploaded content, ensuring that the data is suitable for further analysis. The function will return a message if the data has successfully passed the check and is deemed suitable for further analysis. If it fails, the function will return a 0. The function will perform the check directly onto the mSet$dataSet object, and must be performed immediately after reading in data. The sanity check function evaluates the accuracy of sample and class labels, data structure, deals with non-numeric values, removes columns that are constant across all samples (variance = 0), and by default replaces missing values with half of the original minimal positive value in your dataset.

Usage

SanityCheckData(mSetObj=NA)

Arguments

mSetObj

Input the name of the created mSetObj (see InitDataObjects)
