getintcalib-methods {mscalib}R Documentation

Obtain calibration coefficients using internal calibration

Description

Obtain calibration coefficients using internal calibration.

Arguments

object Massvector-class or Massvectorlist-class
calib Massvector-class with calibratio masses e.g. cal2, cal
error Size of the search window used to find matching masses.
uniq If crossing matches should be resolved
ppm Is the error specified in parts per million or in arbitrary units e.g Dalton
weight should weighted linear regression be used? default is FALSE – no
interfix default FALSE. If TRUE fix the slope if ppm=FALSE, fix intercept otherwise.

Methods

object = "Massvector", calib = "Massvector"
returns Massvector-class
object = "Massvectorlist", calib = "Massvector"
returns Massvectorlist-class

Examples

library(msbase)
data(pldata)
data(cal2)
intcalib <- getintcalib(pldata,cal2,error=400,ppm=TRUE)
image(intcalib,what="Coeff.Intercept")
tmp <- applycalib(pldata,intcalib)
