Convert a lux_spectrum to a different unit

Source: R/lux_spectrum.R
convert_unit.Rd

Converts the spectral values in a lux_spectrum between energy and photon-flux units, or between mW and W for radiance spectra. Supported conversions: "W/m2/nm" \(\leftrightarrow\) "umol/m2/s/nm" / "mmol/m2/s/nm" / "mol/m2/s/nm", and the corresponding "/sr" photonic units. Energy radiance units "W/m2/sr/nm" and "mW/m2/sr/nm" are also interchangeable.

Usage

convert_unit(x, to, ...)

Arguments

x

A lux_spectrum object.

to

Target unit string from the controlled vocabulary.

...

Ignored.

Value

A new lux_spectrum with updated unit and E.

Examples

lam   <- seq(400, 700, by = 10)
x_W   <- lux_spectrum(rep(1, length(lam)), lam, "irradiance", "W/m2/nm")
x_mol <- convert_unit(x_W, "umol/m2/s/nm")
x_mol$unit
#> [1] "umol/m2/s/nm"
