any2T: Convert filter quantities.

In photobiology: Photobiological Calculations

Convert filter quantities.

Description

Functions that convert or add related physical quantities to filter_spct or object_spct objects. transmittance (fraction) into absorptance (fraction).

Usage

any2T(x, action = "add", clean = FALSE)

any2A(x, action = "add", clean = FALSE)

any2Afr(x, action = "add", clean = FALSE)

Arguments

x	an filter_spct or a filter_mspct object.
action	character Allowed values "replace" and "add".
clean	logical replace off-boundary values before conversion

Details

These functions are dispatchers for A2T, Afr2T, T2A, and T2Afr. The dispatch is based on the names of the variables stored in x. They do not support in-place modification of x.

Value

A copy of x with the columns for the different quantities added or replaced. If action = "replace", in all cases, the additional columns are removed, even if no column needs to be added.
