An S3 object of class peakData
A peakData object (see as.peakData for details)
a \(p \times n + 1\) data.frame of expression data, where \(p\) is the number of peaks observed and \(n\) is the number of samples. Each row corresponds to data for each peak/mass
a data.frame with \(n\) rows. Each row corresponds to a sample with one column giving the unique sample identifiers found in e_data column names and other columns providing qualitative and/or quantitative traits of each sample.
a \(p \times 10\) data.frame of meta information for each peak/mass.
Created by running the following code
