l_insert_hinges: Insert wavelength values into spectral data.

Description Usage Arguments Value See Also

View source: R/insert.hinges.r

Description

Inserting wavelengths values immediately before and after a discontinuity in the SWF, greatly reduces the errors caused by interpolating the weighted irradiance during integration of the effective spectral irradiance. This is specially true when data have a large wavelength step size.

Usage

1
l_insert_hinges(x, y, h)

Arguments

x

numeric vector (sorted in increasing order)

y

numeric vector

h

a numeric vector giving the wavelengths at which the y values should be inserted by interpolation, no interpolation is indicated by an empty vector (numeric(0))

Value

a list with variables x and y. Unless the hinge values were already present in y, each inserted hinge, expands the vectors by two values.
