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 applied depends on the class of x and the current value of output options

Usage

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

# S3 method for generic_spct log2(x)

# S3 method for generic_spct log10(x)

# S3 method for generic_spct exp(x)

Value

An object of the same class as 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).
