R: Convert transmittance type.

T2T {photobiology} | R Documentation

## Convert transmittance type.

### Description

Function that allows conversion between internal and total transmittance.

### Usage

    T2T(x, y, byref, Tfr.type.out, ...)

    ## Default S3 method:
    T2T(x, y, byref = NULL, Tfr.type.out = NULL, ...)

    ## S3 method for class 'filter_spct'
    T2T(x, y, byref = FALSE, Tfr.type.out = "total", ...)

    ## S3 method for class 'object_spct'
    T2T(x, y = NULL, byref = FALSE,
      Tfr.type.out = "total", ...)

    ## S3 method for class 'filter_mspct'
    T2T(x, y, byref = FALSE, Tfr.type.out = "total", ...,
      .parallel = FALSE, .paropts = NULL)

    ## S3 method for class 'object_mspct'
    T2T(x, y, byref = FALSE, Tfr.type.out = "total", ...,
      .parallel = FALSE, .paropts = NULL)

### Arguments

`x, y` | R objects
`byref` | logical indicating if new object will be created by reference or by copy of x
`Tfr.type.out` | character One of "total" or "internal"
`...` | 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)

- `default`: Default method

- `filter_spct`: Method for filter spectra

- `object_spct`: Method for object spectra

- `filter_mspct`: Method for collections of filter spectra

- `object_mspct`: Method for collections of object spectra
