localMaxima: localMaxima

In chris-mcginnis-ucsf/MULTI-seq: deMULTIplex is a software suite for MULTI-seq sample barcode FASTQ pre-processing and cell barcode classification.

localMaxima

Description

'localMaxima' is an internal function to 'classifyCells' and 'findReclassCells' which identifies local maxima amongst sample barcode UMI probability density functions.

Usage

 localMaxima(x) 

Arguments

x	Probability-density function, as generated using 'bkde'.

Details

Examples

  model <- approxfun(bkde(barTable.n[,i], kernel="normal"))
  x <-  seq(from=quantile(barTable.n[,i],0.001), to=quantile(barTable.n[,i],0.999),
    length.out=100)
  extrema <- localMaxima(model(x))
