calibexternal.massvectorlist {mscalib} | R Documentation |
Perfroms external calibration of massvectorlist. Obtains the model of the measurment error by getextcalib
and corrects the masses for this error.
## S3 method for class 'massvectorlist': calibexternal(object,ppg,calib,error=300,...)

further parameters. |
calib |
a massvector with exact masses for the massvectors of the calibration samples (ppg). |
error |
relative error of the measurment in (ppm). |
object |
massvectorlist |
ppg |
either a massvector or massvectorlist with masses of the calibration sample (e.g poly-(propylene glycol) ppg) |
In case of external calibration some sample spots are only dedicated to calibration. Calibration samples which produces equidistant peaks, which exact masses are known, can be used to precisely estimate the mass dependent error function.
