vectorial arithmetic for data sets with aplus class
The positive vectors equipped with the perturbation (defined as
the element-wise product) as Abelian sum, and powertransform (defined as the element-wise
powering with a scalar) as scalar multiplication forms a real vector
space. These vector space operations are defined here in a similar way
to +.rmult.
perturbe.aplus(x,y) ## S3 method for class 'aplus' x + y ## S3 method for class 'aplus' x - y ## S3 method for class 'aplus' x * y ## S3 method for class 'aplus' x / y ## Methods for aplus ## x+y ## x-y ## -x ## x*r ## r*x ## x/r power.aplus(x,r)
x |
an aplus vector or dataset of vectors |
y |
an aplus vector or dataset of vectors |
r |
a numeric vector of size 1 or nrow(x) |
The operators try to mimic the parallel operation of R for vectors of
real numbers to vectors of amounts, represented as matrices containing
the vectors as rows and works like the operators for {rmult}
an object of class "aplus" containing the result of the
corresponding operation on the vectors.
