curvPeaks {flowStats}R Documentation

Parse curv1Filter output

Description

Parse the output of curv1Filter and find modes and midpoints of the high-density regions. This function is considered to be internal.

Usage


curvPeaks(x, dat, borderQuant = 0.01, n = 201, from, to, densities=NULL)

Arguments

x A multipleFilterResult produced by a curv1Filter operation.
dat The corresponding flowFrame.
borderQuant A numeric in [0,1] giving the extreme quantiles for which high-density regions are ignored.
n, from, to Arguments are passed on to density.
densities The optional y values of the density estimate computed for the respective data.

Value

A list with items

peaks x and y locations of the modes of the regions in the density estimates.
regions the left and right margins of the regions.
midpoints the mean of regions.
regPoints x and y locations of the outline of the significant density regions.
densFuns an approximation function of the density estimate
