get_peak_info: get peak info

In MoseleyBioinformaticsLab/FTMS.peakCharacterization: Functionality for Detecting and Characterizing Peaks

get peak info

Description

Given a set of points that make up a peak, use the provided method to find the center, intensity and area of the peak.

Usage

get_peak_info(peak_data, peak_method = "lm_weighted", min_points = 4)

Arguments

peak_data	data.frame with mz, intensity, and log intensity log_int
peak_method	which method to use to get information about the peak (see Details)
min_points	how many points have to still be in a peak to return something useful?

Details

This function can choose from several methods to get information about the peak. Currently available methods include:

lm_weighted

quadratic linear fit to log-intensities, with weights for each point relative to the maximum intensity point (current default)

lm_unweighted

quadratic linear fit to log-intensities

Value

data.frame
