write_nad: Writes metadata required for a Proximate application file

In proximetricsR: Spectral Preprocessing and Chemometric Calibration of NIR Sensors

Writes metadata required for a Proximate application file

Description

Internal function for generating a metadata file required for creating a ProxiMate application.

Usage

write_nad(object, path, application_meta, external_properties = NULL, verbose = TRUE)

Arguments

object	a list of models of class spectral_model for which the metadata files should be generated.
path	a string for the directory in which the files will be saved.
application_meta	a list of class application_metadata, containing the metadata for the application. See add_application_metadata.
external_properties	a list of external properties. More details in proximate_write_nax. Defaults to NULL.
verbose	a logical. Should messages about the generated files be printed? Default is TRUE.

Details

This function takes a list of models of class spectral_model and generates the corresponding metadata file (.nad). This file allows the ProxiMate calibration software to import a .nax file. Thus, the main purpose of this file is to added to the zip structure of an application file (.nax). See proximate_write_nax for more details on how this file is used.

Note that it is crucial for all provided models to have some metadata added.

Value

Invisibly returns NULL. Called for its side effect of writing a .nad metadata file to path.
