Get Fitted RT Model

Description

Returns the last fitted RT projection model from a metabCombiner object of type "gam" or "loess".

Usage

getModel(object, fit = c("gam", "loess"))

## S4 method for signature 'metabCombiner'
getModel(object, fit = c("gam", "loess"))

Arguments

object	metabCombiner object
fit	Choice of model, "gam" or "loess"

Value

nonlinear retention time fit object

Examples

data(plasma30)
data(plasma20)
p30 <- metabData(plasma30, samples = "CHEAR")
p20 <- metabData(plasma20, samples = "Red", rtmax = 17.25)
p.comb <- metabCombiner(xdata = p30, ydata = p20, binGap = 0.005)
p.comb <- selectAnchors(p.comb, tolrtq = 0.15, tolQ = 0.2, windy = 0.02)

p.comb <- fit_loess(p.comb, iterFilter = 1, spans = 0.2)
model.gam <- getModel(p.comb, fit = "gam")
