splice: "Splicing" and interpolation of spectra

In inspectr: Storing, manipulating and analysis spectroscopy and associated data in R.

Description

This method mimicks the "splicing" method available in the ViewSpec Pro software from ASD, which aims at correcting steps in the data.

It removes parts of the spectra defined by the wl vector, and interpolates these parts using a method chosen using the method option.

Usage

splice(x, wl)

Arguments

x	a Spectra object
wl	the wavelengths to cut out and interpolate
method	the interpolation method. Available options are "linear", "nearest", "pchip", "cubic", and "spline".

Details

This function is a wrapper around signal::interp1.

Value

an object of same class as x

Examples

data(australia)
spectra(australia) <- sr_no ~ ... ~ 350:2500
oz_spliced <- splice(australia, wl = c(725:1020, 1801:1950), method = "spline")
plot(oz_spliced)
