In CAMERA: Collection of annotation related methods for mass spectrometry data

Description

Todo

Usage

  maxHomologue=4, error=0.002, time=60, intval="maxo",
  plot=FALSE)

Arguments

object	xsAnnotate object
masses	nominal mass and exact mass

maxHomologue	max number of homologue
time	allowed retention time difference between homologues
intval	intensity value (allowed values: maxo,into or intb)
plot	plot hits

Examples

  library(CAMERA)
  library(faahKO)
  xs   <- group(faahko)

  #With specific selected sample
  xsa     <- xsAnnotate(xs)
  #Screen for substance with CH2 differences
  findKendrickMasses(xsa, masses=c(14, 14.01565), plot=TRUE)
