trim_rt: Trims by retention time

In USEPA/LUMA: LCMS-Based Untargeted Metabolomics Assistant

Description

Removes components with retention times smaller than the user specified threshold. See remove_void_volume and CullVoidVolume for examples that use this function.

Usage

trim_rt(object, Peak.list, void.rt, rt.list)

## S3 method for class 'mz'
trim_rt(object, Peak.list, void.rt, rt.list = Peak.list["rt"][[1]])

## S3 method for class 'monoMass'
trim_rt(object, Peak.list, void.rt, rt.list = Peak.list["rt"][[1]])

Arguments

object	used for method dispatch. Can be any object. See usage for details
Peak.list	data frame. Must have column Correlation.stat. Should contain output columns from XCMS and CAMERA, and additional columns from match_Annotation, calc_minfrac, calc_corrstat and plot_metgroup functions.
void.rt	numeric retention time cutoff value corresponding to the LC void volume
rt.list	numeric vector containing retention times for all features or compounds
