teaMerged {alsace} | R Documentation

## Results of an ALS analysis on individual windows

### 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)))
