getintcalib.massvectorlist {mscalib}R Documentation

Internal Calbiration

Description

Obtains error model using massvector with known masses.

Usage

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

Arguments

...
calib massvector with calibration masses
error assumed measurment error.
object massvectorlist
ppm TRUE- describe the error as relative error. FALSE- describe the error as absolute 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.
