organization: organization of a colorSpec object

In colorSpec: Color Calculations with Emphasis on Spectral Data

organization of a colorSpec object

Description

Retrieve or set the organization of a colorSpec object.

Usage

## S3 method for class 'colorSpec'
organization(x)

## S3 replacement method for class 'colorSpec'
organization(x) <- value

Arguments

x	a colorSpec R object
value	a valid organization: 'vector', 'matrix', 'df.col', or 'df.row'.

Details

If organization(x) is "vector", then x is a vector representing a single spectrum. Compare this with stats::ts().

If organization(x) is "matrix", then x is a matrix and the spectra are stored in the columns.

If organization(x) is "df.col", then x is a data.frame with M+1 columns, where M is the number of spectra. The wavelengths are stored in column 1, and the spectra in columns 2:(M+1). This organization is good for printing to the console, and writing to files.

If the organization of x is "df.row", then x is a data.frame with N rows, where N is the number of spectra. The spectra are stored in the last column, which is a matrix with the name "spectra". The other columns preceding spectra (if present) contain extra data associated with the spectra; see extradata.

Value

organization(x) returns a valid organization: 'vector', 'matrix', 'df.col', or 'df.row'.

Note

In organization(x) <- value
if x has more than 1 spectrum, then value equal to 'vector' is invalid and ignored.
If organization(x) is equal to 'df.row' and also has extradata, then changing the organization silently discards the extradata.

Examples

organization(Hoya)              # returns 'df.row'
organization(Hoya) = 'matrix'   # extradata in Hoya is silently discarded
