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)
