falsignal: Find false signal

In liucaomics/genuMet: distinguish genuine signal of untargeted metabolites from measurement artifacts without QC samples

Usage

falsignal(l, cutoffvar = 0.03, cutoffswt = 1, cutofflong = NULL,
  cutoffmr = 0.95)

Arguments

l	A list generated by makefeature.
cutoffvar	Metabolites whose variance >= cutoffvar tend to be false signal.
cutoffswt	Metabolites whose number of switches >= cutoffswt tend to be false signal.
cutofflong	Metabolites whose longest block < cutofflong tend to be false signal.
cutoffmr	Metabolites whose mean missing rate > cutoffmr tend to be false signal

Value

A list contains name lists of predicted false signal.

• mbnames: name list of metabolites.

• wsize: window size.

• ssize: slide size.

• defswitch: definition of switch.

• mrate: missing rate matrix. Each cell of the matrix is a missing rate of a window.

• variance: missing rate variance for each metabolite.

• nswitches: number of switches for each metabolite.

• longestblock: number of windows of the longest block for each metabolite.

• boolbad1: bool vector of type 1 false signal.

• boolbad2: bool vector of type 2 false signal.
