Function that converts absorbance (a.u.) into transmittance (fraction).
A2T(x, action, byref, ...)# S3 method for default
A2T(x, action = NULL, byref = FALSE, ...)
# S3 method for numeric
A2T(x, action = NULL, byref = FALSE, ...)
# S3 method for filter_spct
A2T(x, action = "add", byref = FALSE, ...)
# S3 method for filter_mspct
A2T(x, action = "add", byref = FALSE, ..., .parallel = FALSE, .paropts = NULL)
an R object
a character string
logical indicating if new object will be created by reference or
by copy of x
not used in current version
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.
A copy of x with a column Tfr added and A and
Afr 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.
default: Default method for generic function
numeric: method for numeric vectors
filter_spct: Method for filter spectra
filter_mspct: Method for collections of filter spectra
