The arithmetical operators +, -,
*, /, \^, %%, %/%,
and %*% for hyperSpec objects.
## S4 method for signature 'hyperSpec, hyperSpec': Arith(e1, e2) ## S4 method for signature 'hyperSpec, matrix': Arith(e1, e2) ## S4 method for signature 'matrix, hyperSpec': Arith(e1, e2) ## S4 method for signature 'hyperSpec, numeric': Arith(e1, e2) ## S4 method for signature 'numeric, hyperSpec': Arith(e1, e2) ## S4 method for signature 'hyperSpec, missing': Arith(e1, e2) x %*% y
e1, e2 |
Either two hyperSpec objects or one
hyperSpec object and matrix of same size
as hyperSpec[[]] or a scalar (numeric of length 1).
|
x, y |
Either two hyperSpec objects or one
hyperSpec object and one matrix of appropriate size.

You can use these operators in different ways:
e1 + e2 `+` (e1, e2) x %*% y `%*%`(x, y) -xThe arithmetical operators
+, -, *, /,
^, %%, %/%, and %*% work on the
spectra matrix of the hyperSpec object. They have their
usual meaning (see Arithmetic).
The operators work also with one hyperSpec object and a numeric object
or a matrices of the same size as the spectra matrix of the hyperSpec
object.
With numeric vectors sweep is most probably more appropriate.
If you want to calculate on the data.frame hyperSpec@data, you
have to do this directly on hyperSpec@data.
