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
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.
