Generates a 2^k full factorial design.

1	facDesign(k = 3, p = 0, replicates = 1, blocks = 1, centerCube = 0)

`k`	numeric value giving the number of factors. By default `k` is set to ‘3’.
`p`	numeric integer between ‘0’ and ‘7’. `p` is giving the number of additional factors in the response surface design by aliasing effects. For further information see `fracDesign` and `fracChoose`. By default `p` is set to ‘0’.
`replicates`	numeric value giving the number of replicates per factor combination. By default `replicates` is set to ‘1’.
`blocks`	numeric value giving the number of blocks. By default `blocks` is set to ‘1’. Blocking is only performed for `k` greater 2.
`centerCube`	numeric value giving the number of centerpoints within the 2^k design. By default `centerCube` is set to ‘0’.

facDesign generates 2^k full factorial designs.

The function facDesign returns an object of class facDesign.
