histWeighted: Correlation-weighted histogram of massdiff object

In kbseah/mass2adduct: Mass Spectrometry Imaging Molecular Adduct Finder

Description

Bin mass differences from a massdiff object produced by massdiff into a histogram, with counts weighted by the correlation estimate. The massdiff object must contain the correlation test results, product of corrPairsMSI or corrPairsMSIchunks functions.

Usage

histWeighted(diff, widthFunc = "equal", width = 0.01, ncores = NULL,
  ...)

Arguments

diff	massdiff; Output from function massdiff, containing three numeric vectors (A, B, diff) representing mass peaks and their differences, processed with corrPairsMSI which adds columns Estimate, P.value, and Significance
widthFunc	character; function to use to bin mass differences into histogram. (default "equal", other options to be added)
width	numeric; bin width in m/z units (default 0.01)
ncores	integer; number of processors to use for parallelized implementation. If NULL (default) then run with single processor
...	Other options to be passed to hist()

Value

Object of classes hist and massdiffhist
