spc.interp.spectral: Interpolate spectral values

In PranaGeo/Spectral: Classes and Methods for Working with Spectral Data with Space-Time Attributes

Description

Estimate spectral data at a new set of wavelengths through interpolation using approx().

Usage

spc.interp.spectral(source1,target_lbd,show.plot, ...)

## S4 method for signature 'Spectra'
spc.interp.spectral(source1, target_lbd, show.plot = FALSE)

Arguments

source1	A Spectra object
target_lbd	numeric vector giving desired wavelengths
show.plot	logical TRUE if a graphical representation is required
...	further arguments to pass on to approx().

Examples

sp=spc.example_spectra()
lbd = as.numeric(c(412,440,490,555,670))
sp2 = spc.interp.spectral(sp[,lbd],c(430,450,500))
spc.plot.overlay(SpcList(list(sp,sp2)))

#Quick Plot only the first row
spc.interp.spectral(sp[,lbd],c(430,450,500),show.plot=TRUE)
