chkSpectra: Verify the Integrity of a Spectra or Spectra2D Object

In ChemoSpecUtils: Functions Supporting Packages ChemoSpec and ChemoSpec2D

Verify the Integrity of a Spectra or Spectra2D Object

Description

Utility function to verify that the structure of a Spectra or Spectra2D object is internally consistent. This function should be used after manual editing of these objects. However, in most cases rather than directly editing these objects, one should modify them via:

• removeFreq

• removeSample

• removeGroup

Usage

chkSpectra(spectra, confirm = FALSE)

Arguments

spectra	An object of S3 class ChemoSpec::Spectra() or ChemoSpec2D::Spectra2D().
confirm	Logical indicating whether or not to write the results to the console, as would be desirable for interactive use.

Value

None. When used at the console, and the object is OK, no message is written unless confirm = TRUE. At the console, if there is a problem, messages are issued regardless of the value of confirm.
