cromplot: cromplot

In sipss/AlpsLCMS: Signal processing of LC-MS metabolomics

Description

Function that creates four zoomed plots of a know metabolite to observe the set the parameters for xcms preprocessing. Parameters such as peak width, noise level, or potential neighbors can be studied.

Usage

cromplot(dataset,
rt = 5.8,
mz = 132.102,
metabolite = "(iso)leucine")

Arguments

dataset	a lcms_dataset
rt	known retention time (minutes) of a metabolite that surely is within the dataset. Note that rt critically changes between columns.
mz	known ionized mass of a metabolite that surely is within the dataset.
metabolite	character. The name of the metabolite (for plotting).

Value

Plot of a known chromatographic peak
