rmult: Simple treatment of real vectors

Description

A class to analyse real multivariate vectors.

Usage

rmult(X,parts=1:NCOL(oneOrDataset(X)))

Arguments

X

vector or dataset of numbers considered as elements of a R-vector

parts

vector containing the indices xor names of the columns to be used

Value

• a vector of class "rmult" representing one vector or a matrix of class "rmult", representing multiple vectors by rows.

Details

The rmult class is a simple convenience class to treat data in the scale of real vectors just like data in the scale of real numbers. A major aspect to take into account is that the internal arithmetic of R is different for these vectors.
