Calibprestat-class {mscalib}R Documentation

Class "Calibprestat": peptide rule based calibration

Description

Peptide rule based calibration. Determines calibration coefficients using the algorithm by Wool and Smilansky. This class extends the class Calibstat-class.

Objects from the Class

Objects can be created by call to function getprecalib-methods.

Slots

freq:
Object of class "numeric" : the theoretical peptide frequency (rule) of the database. default = 1.000495
ppm:
Object of class "logical" : (TRUE)
info:
Object of class "character" : unique identifier
tcoor:
Object of class "numeric" : target coordinates
Coeff.Intercept:
Object of class "numeric" : intercept calibration coefficient
Coeff.Slope:
Object of class "numeric" : slope calibration coefficient
lengthmv:
Object of class "numeric" : length of the Massvector-class
quality:
Object of class "numeric" : calibration coefficients quality measure

Extends

Class "Calibstat", directly.
