reorder function

Reorder Multi-Way Factors

Reorders factors from a multiway object.

## S3 method for class 'cpd'
reorder(x, neworder, ...)
## S3 method for class 'indscal'
reorder(x, neworder, ...)
## S3 method for class 'mcr'
reorder(x, neworder, mode = "A", ...)
## S3 method for class 'parafac'
reorder(x, neworder, ...)
## S3 method for class 'parafac2'
reorder(x, neworder, ...)
## S3 method for class 'sca'
reorder(x, neworder, ...)
## S3 method for class 'tucker'
reorder(x, neworder, mode = "A", ...)

Arguments

• x: Object of class "cpd" (output from cpd), "indscal" (output from indscal), class "mcr" (output from mcr), class "parafac" (output from parafac), class "parafac2" (output from parafac2), class "sca" (output from sca), or class "tucker" (output from tucker).
• neworder: Vector specifying the new factor ordering. Must be a permutation of the integers 1 to nfac.
• mode: Character indicating which mode to reorder (only for tucker models). For 3-way Tucker options include "A", "B", and "C". For 4-way Tucker, options are "A", "B", "C", and "D".
• ...: Ignored.

Returns

Same as input.

Details

See cpd, indscal, mcr, parafac, parafac2, sca, and tucker for more details.
