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 relatively large wavelength step size and/or
when the weighting function used has discontinuities in its value or slope.
This function differs from insert_hinges()
in that it returns a vector
of y
values instead of a tibble
.
v_insert_hinges(x, y, h)
A numeric vector with the numeric values of y
, but longer.
Unless the hinge values were already present in y
, each inserted
hinge, expands the vector by two values.
numeric vector (sorted in increasing order).
numeric vector.
a numeric vector giving the wavelengths at which the y values should
be inserted by interpolation, no interpolation is indicated by an empty
numeric vector (numeric(0)
).
