Description

This function sums all the intensities between left-index and right-index.

Usage

1
areaIntegrator(l1, l2, left, right, integrationType, baselineType, fitEMG)

Arguments

l1

(list) A list of time vectors.

l2

(list) A list of intensity vectors.

left

(numeric) left boundary of the peak.

right

(numeric) right boundary of the peak.

integrationType

(string) method to ompute the area of a peak contained in XICs. Must be from "intensity_sum", "trapezoid", "simpson".

baselineType

(string) method to estimate the background of a peak contained in XICs. Must be from "base_to_base", "vertical_division_min", "vertical_division_max".

fitEMG

(logical) enable/disable exponentially modified gaussian peak model fitting.

Value

area (numeric).
