channel: Get the channel numbers of DRIFT-spectrum

In omega1x/spectrotest: Manipulate with DRIFT-spectroscopy data

Description

Get the channel numbers for appropriate wave numbers in the scale of the given object of S3-class drift. The function is a simple backward approximation wavenumber - channel.

Usage

channel(x, wn)

Arguments

x	An object of S3-class drift.
wn	Numeric vector of wavenumbers for which channel numbers should be determined in the DRIFT-spectrum

Value

Numeric vector of channel numbers which are interpolated values of indicies.

 # Get channels of CO2 absorption:
 co2 <- channel(s, c(2268:2277, 2399:2412))
 print(co2)
