Interpolate absorbance data

Interpolates absorbance data to 1 nm resolution so indices can be calculated at wavelengths that were not explicitly measured.

Usage

abs_interp(abs, type = "linear")

Arguments

abs

An abs or abslist object.

type

The interpolation method, either "linear" for linear interpolation using zoo::na.approx(), or "spline" for spline interpolation using zoo::na.spline().

Value

An abs or abslist object.

Examples

abslist_filled <- abs_interp(example_abs)
abs_filled <- abs_interp(example_abs[[1]])
