Catalogues of resolution IV 128 run 2-level fractional factorials up to 33 factors that do have 5-letter words

This package provides catalogues of resolution IV regular fractional factorial designs in 128 runs for up to 33 2-level factors. The catalogues are complete, excluding resolution IV designs without 5-letter words, because these do not add value for a search for clear designs. The previous package version 1.0 with complete catalogues up to 24 runs (24 runs and a namespace added later) can be downloaded from the authors website.


Changes to package FrF2.catlg128

Version 1.2-1, 19/04/2013 made the dominating element of the catalogues informative, instead of including the element "TRUE" for all designs

Version 1.2, 18/04/2013 added designs from 25 to 33 factors (only the even/odd designs, i.e. omitting those without odd words)

The catalogues are now lazy-loaded and provided in one 
sysdata.rda file in the R directory, 
rather than as separate data files in the data directory. 
Thus, the install size of the package has been vastly reduced.
As a consequence, the data() command for loading the catalogues
is no longer needed and does even yield an error message.

Removed file LICENSE in order to get rid of R CMD check note.

Updated maintainer e-mail address

Version 1.1, 29/06/2012 considerably reduced the number of designs included: excluded all even resolution IV designs (i.e. all those without odd words, picked based on those without words of length 5)

Version 1.0-3, 29/06/2012 added a namespace (never went to CRAN, was created for download from homepage)

Version 1.0-2, 04/02/2011 eliminated .Random.seed and .required from each of the rda files

Version 1.0-1, 03/02/2011 removed zipdata = yes, modified rda files to smaller sizes with tools::resaveRdaFiles and added the file for 24 factors to the package

First version on CRAN: Version 1.0, 23/04/2010
