log: Logarithms and Exponentials

Description

Logarithms and Exponentials for Spectra. The functions are applied to the spectral data, not the wavelengths. The quantity in the spectrum to which the function is appled depends on the class of x and the current value of output options

Usage

## S3 method for class 'generic_spct':
log(x, base = exp(1))

log2.generic_spct(x)

log10.generic_spct(x)

## S3 method for class 'generic_spct':
exp(x)

Arguments

x

an object of class "generic_spct"

base

a positive number: the base with respect to which logarithms are computed. Defaults to e=exp(1).
