getLOESSfit: Calculates LOESS fit between RT of two runs

In Roestlab/DIAlign: Dynamic Programming Based Alignment of MS2 Chromatograms

Description

This function selects features from oswFiles which has m-score < maxFdrLoess. It fits LOESS on these feature. Loess mapping is established from reference to experiment run.

Usage

getLOESSfit(oswFiles, ref, eXp, maxFdrGlobal, spanvalue = 0.1)

Arguments

oswFiles	(list of data-frames) it is output from getFeatures function.
ref	(string) Must be a combination of "run" and an iteger e.g. "run2".
eXp	(string) Must be a combination of "run" and an iteger e.g. "run2".
maxFdrGlobal	(numeric) A numeric value between 0 and 1. Features should have m-score lower than this value for participation in LOESS fit.
spanvalue	(numeric) Spanvalue for LOESS fit. For targeted proteomics 0.1 could be used.

Value

An object of class "loess".
