prefilter: Prefilter

In Miso: Multi-Isotope Labeling for Metabolomics Analysis

Description

prefiltering isotopically labeled analytes according to the experiment design.

Usage

prefilter(xset, subgroup = NULL, unlabel = NULL, reps = TRUE,
  p = 0.05, folds = 10)

Arguments

xset	xcms object.
subgroup	subset the xcms groups. The name should be the same as in phboData$class. default = NULL, which means no subset will be performed.
unlabel	specify which is unlabeled group.
reps	if there are replicates in the sample.
p	p-value threshold, default value = 0.05
folds	fold change threshold, default value = 10

Value

a filtered peaklist

Examples

data(lcms)
explist <- prefilter(lcms, subgroup = c("B", "C", "D"), unlabel = "B")
