Peak Summarization

Description

Summarize peaks based on their shapes and properties.

Usage

# Get peak widths
peakwidths(x, peaks, domain = NULL,
    fmax = 0.5, ref = c("height", "prominence"))

# Get peak areas
peakareas(x, peaks, domain = NULL)

# Get peak heights
peakheights(x, peaks)

Arguments

x	A numeric vector.
peaks	The indices (or domain values) of peaks for which the widths or areas should be calculated.
domain	The domain variable of the signal.
fmax	The fraction of the peak's height used for determining the peak's width.
ref	The reference value of the peak for determining the peak width: either the peak height of the peak prominence.

Value

A numeric vector giving the widths, areas, or heights of the peaks with attributes 'left_bounds' and 'right_bounds' giving the left and right boundaries of the peak.
