Locally align a pair of mass specs

Description

Locally align a pair of mass specs

Usage

msms_align(
  data1,
  data2,
  mass,
  alim = c(-1, 6),
  laglim = 0.3,
  by = 0.005,

  verbose = T
)

Arguments

data1	the first MS
data2	the secon MS
mass	the mass around which to do the alighment
alim	the window around the mass, defaluts to [-1,6]
laglim	the largest permissable lag
by	the resampling rate, default value is 0.005
doplot	whether to generate a plot of the alignment
verbose	whether to write messages whilst processing

Value
