correctinternal.massvectorlist {mscalib} | R Documentation |
Determines the measurment error of the masses using getintcalib.massvectorlist
. It refines the error model and applies it to the massvector by applyintcalib.massvectorlist
.
## S3 method for class 'massvectorlist': correctinternal(object,calib,error=500,ppm=TRUE,...)

calib |
massvector with calibration masses |

assumed measurment error. |

ppm |
logical;TRUE - describe the error as relative error. FALSE - describe the error as absolute error. |
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.
