Peel {ImpuR}R Documentation

bilinear model by peeling

Description

Iteratively compute bilinear components (left and right vectors) by projection pursuit. Starts by finding the apex spectrum or chromatogram (according to peel.specfirst) over a window around the "summit" given by margin. Then continues by deflation.

Usage

Peel(object, threshold = 1, direction = c("left", "right", "left", "right"), specfirst = TRUE, margin = 3, favor.positive = FALSE)

Arguments

object a spectime object
threshold whether the apex should be used (threshold=1) or a value a bit lower (threshold<1).
direction whether to peek from left (top) or right (bottom).
specfirst whether to extract the spectrum before the chromatogram
margin peel margin
favor.positive whether to favor positive components

Value

a spectime object with slots @ct and @spec filled in
