A2T: Convert absorbance into transmittance

Description

Function that converts absorbance (a.u.) into transmittance (fraction).

Usage

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)

Value

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.

Arguments

x

an R object.

action

a character string "add" or "replace".

byref

logical indicating if new object will be created by reference or by copy of x.

...

not used in current version.

.parallel

if TRUE, apply function in parallel, using parallel backend provided by foreach

.paropts

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.

Methods (by class)

• A2T(default): Default method for generic function

• A2T(numeric): method for numeric vectors

• A2T(filter_spct): Method for filter spectra

• A2T(filter_mspct): Method for collections of filter spectra
