Either two hyperSpec objects or one hyperSpec
object and matrix of same size as hyperSpec[[]] or a scalar
(numeric of length 1).
As hyperSpec objects must have numeric spectra matrices, the
resulting matrix of the comparison is returned directly.

two hyperSpec objects that are tested for
equality

handed to all.equal when testing the slots of the
hyperSpec objects
check.attributes,check.names
see all.equal
check.column.order
If two objects have the same data, but the order
of the columns (determined by the names) differs, should they be regarded
as different?
check.label
Should the slot label be checked? If the
labels differ only in the order of their entries, they are conidered
equal.
Details
all.equal checks the equality of two hyperSpec objects.
The comparison operators >, <, >=, <=,
==, and != work on the spectra matrix of the hyperSpec
object. They have their usual meaning (see Comparison).
The operators work also with one hyperSpec object and a numeric
(scalar) object or a matrices of the same size as the spectra matrix of the
hyperSpec object.
With numeric vectors sweep might be more
appropriate.
If you want to calculate on the data.framehyperSpec@data,
you have to do this directly on hyperSpec@data.
Value
a logical matrix for the comparison operators.
all.equal returns either TRUE, or a character vector describing the
differences. In conditions, the result must therefore be tested with
isTRUE.
