integrate_xy {photobiology} | R Documentation

## Gives irradiance from spectral irradiance.

### Description

This function gives the result of integrating spectral irradiance over wavelengths.

### Usage

    integrate_xy(x, y)

### Arguments

`x` | numeric vector.
`y` | numeric vector.

### Value

a single numeric value with no change in scale factor: e.g. [W m-2 nm-1] -> [W m-2]
