R: Transformation NMF Model Objects

t.NMF {NMF} | R Documentation

## Transformation NMF Model Objects

### Description

`t` transpose an NMF model, by transposing and swapping its basis and coefficient matrices: t([W,H]) = [t(H), t(W)].

### Usage

      ## S3 method for class 'NMF'
     t(x)

### Arguments

`x` | NMF model object.

### Details

The function `t` is a generic defined in the base package. The method `t.NMF` defines the trasnformation for the general NMF interface. This method may need to be overloaded for NMF models, whose structure requires specific handling.

### See Also

Other transforms: `nneg`, `posneg`, `rposneg`

### Examples

    x <- rnmf(3, 100, 20)
    x
    # transpose
    y <- t(x)
    y

    # factors are swapped-transposed
    stopifnot( identical(basis(y), t(coef(x))) )
    stopifnot( identical(coef(y), t(basis(x))) )
