vectorial arithmetic for data sets with aplus class
Description
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.
Usage
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)
Arguments
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) |
Details
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}
Value
an object of class "aplus" containing the result of the
corresponding operation on the vectors.
