eem_set_wavelengths {eemR}

Set Excitation and/or Emission wavelengths

Description

This function allows to manually 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

An object of class eemlist.

ex

A numeric vector of excitation wavelengths.

em

A numeric vector of emission wavelengths.

Value

An object of class eemlist.

Examples

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

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

plot(eem)
