teaMerged: Results of an ALS analysis on individual windows

In rwehrens/alsace: ALS for the Automatic Chemical Exploration of mixtures

Description

Object of class ALS: the result of the analysis of the tea data, using three time windows with an overlap parameter of 10. The three ALS models have been merged into one ALS object, which can be inspected and used for further analysis.

Usage

data(teaMerged)

Examples

## generation of the data
data(tea)
new.lambdas <- seq(260, 500, by = 2)
tea <- lapply(tea.raw,
              preprocess,
              dim2 = new.lambdas)
tea.split <- splitTimeWindow(tea, c(12, 14), overlap = 10)
tea.alslist <- lapply(tea.split,
                      function(Xl) {
                        Xl.opa <- opa(Xl, 4)
                        doALS(Xl, Xl.opa)
                      })
teaMerged <- mergeTimeWindows(tea.alslist)
## This is the object saved in teaMerged.RData

ncomp <- ncol(teaMerged$S)
myPalette <- colorRampPalette(c("black", "red", "blue", "green"))
mycols <- myPalette(ncomp)

plot(teaMerged, what = "spectra", col = mycols)
legend("top", col = mycols, lty = 1, bty = "n", ncol = 2,
       legend = paste("C", 1:ncol(teaMerged$S)))
