The comparison operators >
, <
, >=
, <=
, ==
, and !=
for hyperSpec
objects.
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 base::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
.

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
base::isTRUE()
.
sweep-methods()
for calculations involving
a vector and the spectral matrix.
methods::S4groupGeneric()
for group generic methods.
base::Comparison()
for the base comparison functions.
Arith()
for arithmetic operators,
Math()
for mathematical group generic functions
(groups Math and Math2) working on hyperSpec
objects.
