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
.
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.

equality
handed to all.equal
when testing the slots of the
hyperSpec
objects
see all.equal
If two objects have the same data, but the order of the columns (determined by the names) differs, should they be regarded as different?
Should the slot label
be checked?
If the
labels differ only in the order of their entries, they are conidered
equal.

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.frame
hyperSpec@data
,
you have to do this directly on hyperSpec@data
.
