findMainPeak: Helper function to find the main peak of a distribution

In refineR: Reference Interval Estimation using Real-World Data

Helper function to find the main peak of a distribution

Description

The function uses a combination of the area under the curve between valleys and the peak height to detect the main peak.

Usage

findMainPeak(x, ab, mStart, withHeight = FALSE, prevPeak = NULL)

Arguments

x	(numeric) vector of data points
ab	(numeric) vector specifying the lower and higher truncation limit of density estimation
mStart	(integer) specifying the width of the smoothing kernel(s) used for density estimation
withHeight	(logical) specifying if only the area under the curve (FALSE) or a combination of AUC and peak height (TRUE) should be used to detect the main peak
prevPeak	(numeric) specifying the modEst of the previously estimated peak

Value

(list) with the two numeric values peakInd, modEst, and a density list
