Aligned Peak Property Table Correlation List Calculator

Description

Aligned Peak Property Table Correlation List Calculator

Usage

alignedPeakPropertyTableCorrelationListCalculator(peakPropertyTable,
RTtolerance = 0.05, minFreqDetection = 3, minRatioDetection = 0.01,
method = "pearson", minThresholdCorrelation = 0, number_processing_threads = 1)

Arguments

peakPropertyTable	peak property table such as ‘peak_height', 'peak_area’ and ‘peak_R13C’
RTtolerance	retention time tolerance (min)
minFreqDetection	minimum frequency of detection for a (m/z-RT) peak across the peak property table
minRatioDetection	minimum ratio of detection for a (m/z-RT) peak across the peak property table. This value should be between (0 - 1).
method	a character string indicating which correlation coefficient (or covariance) is to be computed. One of "pearson" (default), or "spearman": can be abbreviated. (from 'cor' function of the 'stats' package)
minThresholdCorrelation	minimum threshold for the correlation method
number_processing_threads	number of processing threads

Value

A list of related peak IDs for each individual (m/z-RT) pair on the peak property table
