collection(...)

# S3 method for default
collection(...)

# S3 method for collection
tidy(x, ...)

Arguments

...	further arguments passed to or from other methods(not currenctly used).
x	A collection object.

Value

An object of class collection with sub-objects:

data

A tibble that contains the spectral data

normalized

Information about the normalization of the dataset

bucketted

Information about the bucketting of the dataset

labels

Information about the labelling of the dataset

A tibble with a variable number columns depending on the binning of the data:

id

Unique sample identifier

label

Label for the sample

bins

Bin centers

Details

The collection is empty on creation, use add_spectrum to populate it. It is recommended to populate a collection using purrr::walk on a list of files (see add_spectrum).
