Function that converts transmittance (fraction) into absorptance (fraction). If reflectance (fraction) is available, it allows conversions between internal and total absorptance.

A copy of x
with a column Tfr
added and other columns
possibly deleted except for w.length
. If action = "replace"
,
in all cases, the additional columns are removed, even if no column needs
to be added.
an R object
character Allowed values "replace" and "add"
logical indicating if new object will be created by reference or by copy of x
logical replace off-boundary values before conversion
not used in current version
numeric vector. Spectral reflectance o reflectance factor.
Set to zero if x
is internal reflectance,
if TRUE, apply function in parallel, using parallel backend provided by foreach
a list of additional options passed into the foreach function when parallel computation is enabled. This is important if (for example) your code relies on external data or packages: use the .export and .packages arguments to supply them so that all cluster nodes have the correct environment set up for computing.
