is_normalized: Query whether a generic spectrum has been normalized.

In photobiology: Photobiological Calculations

Query whether a generic spectrum has been normalized.

Description

This function tests a generic_spct object for an attribute that signals whether the spectral data has been normalized or not after the object was created.

Usage

is_normalized(x)

is_normalised(x)

Arguments

x	An R object.

Value

A logical value indicating if x is normalized or not, for collections of spectra, a named list with logicals as members. If x is not a generic_spct or generic_mspct object the value returned is NA.

Note

While method getNormalized() returns in some cases numeric values or possibly even character values if stored in attribute normalized, is_normalized() always returns a logical value and can be safely used in conditional code clauses.

is_normalised() is another name for is_normalized().
