 rmult(X,parts=1:NCOL(oneOrDataset(X)),orig=attr(X,"orig"),
                missingProjector=attr(X,"missingProjector"))
 ## S3 method for class 'rmult'
print(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

x

an rmult object

orig

the original untransformed dataset

missingProjector

the Projector on the observed subspace

...

further generic arguments passed to print.default

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.

Value

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