filter_peaks: Filter peak lists

In chromatographR: Chromatographic Data Analysis Toolset

Filter peak lists

Description

Utility function to remove peaks from a peak list, e.g. because their intensity is too low. Currently one can filter on peak height, peak area, standard deviation, and/or retention time.

Usage

filter_peaks(peak_list, min_height, min_area, min_sd, max_sd, min_rt, max_rt)

Arguments

peak_list	A peak_list object, consisting of a nested list of peak tables, where the first level is the sample, and the second level is the spectral component. Every component is described by a matrix where every row is one peak, and the columns contain information on retention time, full width at half maximum (FWHM), peak width, height, and area.
min_height	Minimum peak height.
min_area	Minimum peak area.
min_sd	Minimal standard deviation.
max_sd	Maximum standard deviation.
min_rt	Minimum retention time.
max_rt	Maximum retention time.

Value

A peak list similar to the input, with all rows removed from that do not satisfy the specified criteria.
