eemR (version 0.1.2)

eem_set_wavelengths: Set Excitation and/or Emission wavelengths

Description

This function allows to manully specify either excitation or emission vector of wavelengths in EEMs. This function is mostly used with spectrophotometers such as Shimadzu that do not include excitation wavelengths in fluorescence files.

Usage

eem_set_wavelengths(eem, ex, em)

Arguments

eem

Either an object of class eem or eemlist.

ex

A numeric vector of excitation wavelengths.

em

A numeric vector of emission wavelengths.

Value

• Either an object of class eem or eemlist.

Examples

folder <- system.file("extdata/shimadzu", package = "eemR")

eem <- eem_read(folder)
eem <- eem_set_wavelengths(eem, ex = seq(230, 450, by = 5))

plot(eem)
