Close match PPM

Description

Matches peaks between two spectra.

Usage

closeMatchPpm(x, y, xidx, yidx, xolength, dppm, dmz)

Arguments

x

sorted M/Z values (ascending order) of input spectrum (no NA).

y

sorted M/Z values (ascending order) of reference spectrum (no NA).

xidx

indices of the M/Z peaks of x, taken from the original spectrum ordered in decreasing intensity values.

yidx

indices of the M/Z peaks of y, taken from the original spectrum ordered in decreasing intensity values.

xolength

The length of the output.

dppm

The M/Z tolerance in PPM.

dmz

Minimum M/Z tolerance.

Value

A list of results.
