Plot Specfeat

Description

Plot spectra in objects of class Specfeat. Specfeats contain spectral data after applying a transformation such as continuum removal (see function transformSpeclib.

Usage

## S4 method for signature 'Specfeat'
plot(x, fnumber = 1:n_features(x), stylebysubset = NULL,
        changecol = TRUE, changetype = FALSE, autolegend = TRUE, new = TRUE,
        ...)

Arguments

`x`	Object to be plotted
`fnumber`	Subscript of feature(s) to be plotted
`stylebysubset`	Name of column in SI table to be used for colour.
`changecol`	Flag indicating if line colours change according to values in coloumn defined by stylebysubset
`changetype`	Flag indicating if line types change according to values in coloumn defined by stylebysubset
`autolegend`	Flag if legend is plotted.
`new`	Flag if a new plot should be started.
`...`	Further arguments passed to `plot.default`

Examples

## Not run: 
data(spectral_data)

## Transform speclib
bd <- transformSpeclib(spectral_data, method = "sh", out = "bd")

##Example to isolate the features around 450nm, 700nm, 1200nm and 1500nm.
featureSelection <- specfeat(bd, c(450,700,1200,1500))

## Plot features
plot(featureSelection)

## Advanced plotting example
plot(featureSelection, 1:2, stylebysubset = "season")

plot(featureSelection, 1:2, stylebysubset = "season", changecol = FALSE, 
     changetype = TRUE)

## End(Not run)
