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.
filter_peaks(peak_list, min_height, min_area, min_sd, max_sd, min_rt, max_rt)A peak list similar to the input, with all rows removed from that do not satisfy the specified criteria.
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.
Minimum peak height.
Minimum peak area.
Minimal standard deviation.
Maximum standard deviation.
Minimum retention time.
Maximum retention time.
