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