proximateCannabis

Description

Selected samples of cannabis NIR measurements for demo purposes. The dataset contains absorbance spectra of 80 cannabis samples measured between 1001 nm and 1700 nm at a 3 nm interval. A total number of four reference vectors is included: "CBDA" (Cannabidiolic acid), "THCA" (Tetrahydrocannabinolic acid), "CBD" (Cannabidiol) and "THC" (Tetrahydrocannabinol).

Usage

data("proximateCannabis")

Format

A data.frame containing 80 observations of four response variables, with their corresponding spectral data.

Details

This dataset is an example for a typical data file for ProxiMate applications, with a total of 80 cannabis samples, selected as a subset of a larger database.

Note that this dataset is unrelated to proxiscoutCannabis, which contains a different set of cannabis samples, measured with ProxiScout devices over a different spectral range and accompanied by a different set of reference variables. The two datasets share neither samples nor reference values and cannot be combined.

It contains the following rows for each observation:

• ROW: Integers for the associated numbers inside the database.

• Check: Characters, indicating whether the particular observation should be included in the construction of the model inside a ProxiMate.

• Date: Characters for the date and time when the measurement was taken.

• SNR: Characters of the serial number of the involved ProxiMate device.

• ID: Characters for the ID's.

• Barcode: Characters for the barcodes.

• Notes: Characters for the notes.

• Result: Characters for the results.

• Reference: Characters containing all reference values, concatented into one character with semicolon separation.

• CBDA: Numerics for the reference values of Cannabidiolic acid.

• THCA: Numerics for the references values of Tetrahydrocannabinolic acid.

• CBD: Numerics for the reference values of Cannabidiol.

• THC: Numerics for the reference values of Tetrahydrocannabinol.

• Begin: Characters, indicating when the measuring was initiated.

• End: Characters, indicating when the measurement was completed.

• Recipe: Characters for the recipe.

• Composition: Characters for the composition of the sample.

• Images: Characters for the image of the samples.

• spc: A numerical matrix of the absorbance spectra, corresponding to each individual observation.
