get-methods | R Documentation |
Simple functions to allow abstracted access to components of a
permutation design, for example as returned by
how
. Whilst many of these are very simple index
opertations on a list, using these rather than directly accessing that
list allows the internal representation of the permutation design to
change without breaking code.

These are extractor functions for working with permutation design
objects created by how
. They should be used in
preference to directly subsetting the permutation design in case the
internal structure of object changes as permute is developed.
getHow
is an alias for getControl
; specific methods are
implemented for getControl
if you are debugging.
These are simple extractor functions and return the contents of the
corresponding components of object
.

, a utility function for checking
permutation scheme described by how
.
