e2q: Convert energy-based quantities into photon-based quantities.

Description

Function that converts spectral energy irradiance into spectral photon irradiance (molar).

Usage

e2q(x, action, byref, ...)

# S3 method for default e2q(x, action = "add", byref = FALSE, ...)

# S3 method for source_spct e2q(x, action = "add", byref = FALSE, ...)

# S3 method for response_spct e2q(x, action = "add", byref = FALSE, ...)

# S3 method for source_mspct e2q(x, action = "add", byref = FALSE, ..., .parallel = FALSE, .paropts = NULL)

# S3 method for response_mspct e2q(x, action = "add", byref = FALSE, ..., .parallel = FALSE, .paropts = NULL)

Arguments

x

an R object

action

a character string

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)

  • default: Default method

  • source_spct: Method for spectral irradiance

  • response_spct: Method for spectral responsiveness

  • source_mspct: Method for collections of (light) source spectra

  • response_mspct: Method for collections of response spectra
