correctinternal.massvectorlist {mscalib}R Documentation

Internal Calibration

Description

Determines the measurment error of the masses using getintcalib.massvectorlist. It refines the error model and applies it to the massvector by applyintcalib.massvectorlist.

Usage

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

Arguments

...
calib massvector with calibration masses
error assumed measurment error.
object massvectorlist
ppm logical;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

massvectorlist calibrated massvectorlist.
