normalize_zero_one_scaling {pmartR}

Scale from zero to one

Description

Perform scaling of data from zero to one.

Usage

normalize_zero_one_scaling(omicsData)

Arguments

omicsData

an object of the class 'pepData', 'proData', 'metabData', 'lipidData', 'nmrData', created by as.pepData, as.proData, as.metabData, as.lipidData, as.nmrData, respectively.

Details

The sample-wise minimum of the features is subtracted from each feature in e_data, then divided by the difference between the sample-wise minimum and maximum of the features to get the normalized data. The location estimates are not applicable for this data and the function returns a NULL list element as a placeholder. The scale estimates are the sample-wise feature ranges. All NA values are replaced with zero.

Value

Normalized omicsData object of class 'pepData', 'proData', 'metabData', 'lipidData', 'nmrData', created by as.pepData, as.proData, as.metabData, as.lipidData, as.nmrData, respectively.
