do_emsc: Perform EMSC

In bpollner/aquap2: Multivariate Data Analysis Tools for R including Aquaphotomics Methods

Perform EMSC

Description

Performs EMSC with up to two signals on the provided dataset

Usage

do_emsc(dataset, vecLoad = NULL, exportModel = FALSE)

Arguments

dataset	An object of class 'aquap_data" as produced by gfd or as can be extracted from a 'cube' via getcd.
vecLoad	A data frame x (ncol(x) <= 2) with one or two loading vectors or one regression vector.
exportModel	Logical. If a possible model should be stored in the set, (leave at FALSE).

Details

A data frame with one or two loadings or with one regression vector can be used as input to (try to) remove the effect on the data described by said loadings / regr. vector. For example, from a pca-model the first and second loading vector can be extracted with pcaModel$loadings[, c(1,2)].

Value

Returns the dataset with the transformed NIR data.

See Also

getcm for easy extraction of single models where loading vectors or a regression vector can be obtained.

Examples

## Not run: 
fd <- gfd()
cu <- gdmm(fd, getap(do.pca=TRUE)) # assumes no split
loadings <- getcm(cu, 1, what="pca")$loadings[, c(1,2)]
fd_emsc <- do_emsc(fd, loadings)
