Utilitiy functions for the EBarrays package

1 | ```
ebPatterns(x, ordered=FALSE)
``` |

`x` |
x can be a character vector (of length > 2) (see example), or an
arbitrary connection which should provide patterns, one line for
each pattern. If |

`ordered` |
logical variable specifying whether the pattern is ordered or not |

`ebPatterns`

creates objects that represent a collection of
hypotheses to be used by `emfit`

.

`ebPatterns`

creates an Object of class “ebarraysPatterns”, to
be used in other functions such as `emfit`

. This is
nothing more than a list (and can be treated as such as far as
indexing goes) and is used only for method dispatch.
