getextcalib.massvector {mscalib} | R Documentation |
Returns the error model obtained from the calibration sample.
## S3 method for class 'massvector': getextcalib(object,calib,error=300,...)

|
calib |
massvector with calibration masses |
error |
relative measurment error in ppm. |
object |
massvector |
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.
calibspline |
can be used to calibrate peaklists |
