Function that converts transmittance (fraction) into absorbance (a.u.).
T2A(x, action, byref, clean, ...)# S3 method for default
T2A(x, action = NULL, byref = FALSE, ...)
# S3 method for numeric
T2A(x, action = NULL, byref = FALSE, clean = TRUE, ...)
# S3 method for filter_spct
T2A(x, action = "add", byref = FALSE, clean = TRUE, ...)
# S3 method for filter_mspct
T2A(
x,
action = "add",
byref = FALSE,
clean = TRUE,
...,
.parallel = FALSE,
.paropts = NULL
)
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
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 A 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.
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
