proximate_write_model: Write calibration (.cal), project (.prj) and report (.rtf)...

In proximetricsR: Spectral Preprocessing and Chemometric Calibration of NIR Sensors

Write calibration (.cal), project (.prj) and report (.rtf) files to a specified directory

Description

\loadmathjax

This function allows to write native ProxiMate calibration, project and report files from a spectral_model object.

Usage

proximate_write_model(object, path, tsv_paths, application_name = "Untitled",
                      cal = TRUE, prj = TRUE, rtf = TRUE,
                      verbose = TRUE, internal_prj_path = NULL)

Arguments

object	a list of models of class spectral_model. These models should be generated using the calibrate function.
path	a string for the directory in which the files should be saved.
tsv_paths	a vector of character strings for the paths (including the names) of the tsv data files. See details.
application_name	a string with the name of the generated files. Defaults to "Untitled".
cal	a logical. Should a calibration file (.cal) be written? Default is TRUE.
prj	a logical. Should a project file (.prj) be written? Default is TRUE.
rtf	a logical. Should a report in rich text format (.rtf) be written? Default is TRUE.
verbose	a logical. Should progress bars for the generated files be printed? Default is TRUE.
internal_prj_path	a string. Only used for changing the path printed on the first line of the project file. This is necessary mainly for calls from proximate_write_nax, as it creates the project file in a temporary file, which would also store that temporary path into the project file. This argument allows you to overwrite that path individually. Otherwise, this parameter may be ignored. If NULL (default), will be set to path.

Details

This function generates files with extensions ".prj" (project file), ".cal" (calibration file), and ".rtf" (report) for the provided models of class spectral_model in the argument object. Each file type can be individually enabled or disabled via the cal, prj, and rtf arguments. All files will be named according to the chosen name of the application (given by application_name). Note that in contrast to proximate_write_nax, the metadata does not influence the name of the application. This allows models to be passed directly to this function without the need for metadata. Additionally, the name of the response variable is automatically added to the names of the produced files, so that all generated files have unique names.

Value

Invisibly returns NULL. Called for its side effect of writing calibration, project and/or report files to path.

data("proximateCannabis")
control <- calibration_control(validation_type = "kfold", number = 3, folds = "sequential")
amodel <- calibrate(CBDA ~ spc,
  data = proximateCannabis, preprocess = preprocess_recipe(),
  method = fit_plsr(5), control = control, verbose = FALSE
)
