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("NIRcannabis")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. 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.
