Objects from the Class
Objects can be created by calls of the form new("MassArrayPeak", ID, MW.theoretical, MW.actual, probability, SNR, height, sample.intensity, ref.intensity, sequence, adduct, type, charge, collisions, components, missing, new, ...).Slots
ID:- Peak ID inicating indexed position within a potentially large list of peaks
MW.theoretical:- Expected molecular weight of peak based on nucleotide sequence
MW.actual:- Observed molecular weight from experimental data
probability:- Object of class
"numeric" ~~ SNR:- Signal-to-noise ratio
height:- Raw peak height
sample.intensity:- Raw sample intensity
ref.intensity:- Object of class
"numeric" ~~ sequence:- Nucleotide composition or sequence(s) corresponding to peak
adduct:- One of 'Na', 'K', or '' indicating whether or not peak represents a salt adduct of another expected peak
type:- Object of class
"character" ~~ charge:- Degree of ionization of fragment (default is '1' indicating a single positive charge per fragment)
collisions:- Number of peaks that share the same molecular weight as the current peak
components:- Number of fragments expected to give rise to a peak of this molecular weight
missing:- Logical indicating whether or not the expected peak is missing from the spectral data
new:- Logical indicating whether or not the observed peak is unexpected given the amplicon sequence
