peakDetect: Automatic peak detection

Description Usage Arguments Value

View source: R/ClusterX.R

Description

Automatic detect peaks by searching high denisty point with anomalous large distance to higher denisty peaks. rho and delta are transformed to one index, and the anomalous peaks are detected using generalized ESD method.

Usage

1
peakDetect(rho, delta, alpha = 0.001)

Arguments

rho

A vector of the local density, outout of localDensity

delta

A vector of distance to closest observation of higher density

alpha

The level of statistical significance for peak detection.

Value

a vector containing the indexes of peaks
