calibexternal.massvector {mscalib} | R Documentation |
Perfroms external calibration. Obtains the error model by calling getextcalib
and corrects the masses in the massvector for the errror.
## S3 method for class 'massvector': calibexternal(object,ppg,calib,...)

further parameters. |
calib |
a massvector with exact masses of the calibration sample (ppg). |
object |
massvector |
ppg |
either a massvector or massvectorlist with masses of the calibration sample (e.g. poly-(propylene glycol)). |
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.
