Peel {ImpuR} | R Documentation |
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.
Peel(object, threshold = 1, direction = c("left", "right", "left", "right"), specfirst = TRUE, margin = 3, favor.positive = FALSE)
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 |
a spectime
object with slots @ct and @spec filled in
