getintcalib.massvector {mscalib}R Documentation

Internal Calbiration.

Description

Obtains error model by alingning masses in massvector to known masses (calibration list).

Usage

## S3 method for class 'massvector':
getintcalib(object,calib,error=500,uniq=FALSE,ppm=TRUE,...)

Arguments

...
calib massvector with calibration masses
error assumed measurment error.
object massvector
ppm TRUE- describe the error as relative error. FALSE- describe the error as absolute error.
uniq TRUE- use only mass closest to calibration mass. FALSE- use all masses closer to the calibration mass then given error.

Details

Internal calibration aligns masses of peaks to known masses and determines by linear regression a affine function that describing the relative error. The internal correction fails when no calibration peaks can be found.

Value

calibintstat object of class calibintstat.
