In hhabra/Combiner: Method for Combining LC-MS Metabolomics Feature Measurements

Retrieve Filtered Features

Description

Returns a data frame of metabolomics features eliminated in the metabData step. Features are returned based on the specific filter used for their elimination (RT, missingness, or duplicates).

Usage

filtered(object, type = c("rt", "duplicates", "missing"))

## S4 method for signature 'metabData'
filtered(object, type = c("rt", "missing", "duplicates"))

Arguments

object	metabData object
type	one of three filter types used for feature removal

Value

data frame of features removed due to specified filter

Examples

data(plasma20)

p20 <- metabData(plasma20, samples = "CHEAR", zero = TRUE, misspc = 20,
                  rtmax = 17)

filtered_by_rt <- filtered(p20, type = "rt")

filtered_by_missingness <- filtered(p20, type = "missing")
