QuantData: Quantitative data after data pre-processing and quality control of MS runs
Description
This is an example of quantitative data after data pre-processing and quality control of MS runs (i.e., transformation, normalization, and filtering of the original intensities measurements) and can be obtained directly from dataProcess.
Usage
QuantData
Arguments
Format
data.frame
Details
The quantitative data after data pre-processing and quality control of MS runs not only contain the same variable from the raw data, but with addition variables for statistical model fitting and group comparison. For examples, Variable ABUNDANCE represents the final measurement, which could be normalized or not depending on the options you specified in dataProcess. Default option in dataProcess is with log2 transformation and normalization.
