~~ Internal functions, mainly for deriving words, alias structures and so forth from catalogue information for regular 2-level fractional factorials. They need not be accessed for normal use of the package - some of them may be made user-usable for future versions of the package.
The constant Yates is user-visible, as it can be useful for expert users. ~~

liste |
list of words in terms of vectors of factor numbers to be combined into one new word |
string.vec |
vector of words in terms of factor letter combinations (e.g. “ABC”) to be combined into one new word |
sep |
character by which interaction terms are separated or concatenated; default is empty, i.e. ABC are separated into A, B and C; for more than 50~factors, a colon is needed so that F1:F2:F127 can be separated into F1, F2 and F127, for example. |

character string that contains a name of a design from |
max.length |
the maximum word length to be calculated for the words list; in large design, choosing this to be 4 or 5 may substantially speed things up! |

Yates
is a user-visible constant that is useful in design construction:
Yates
is a list of design column generators in Yates order (for 4096 runs), e.g. Yates[1:8]
is identical to
list(1,2,c(1,2),3,c(1,3),c(2,3),c(1,2,3))
.
mult.gen
and mult.gen.a
determine a new word as the product of the argument words (numeric vector or character string respectively),
words.all
calculates a word list object with word length pattern, the word list itself and a max.length entry,
alias3fi
calculates an alias pattern based on the structure of the design (less demanding than the word list approach.
gen.check
produces a list of vectors with integers from 1 to k for denoting the generators,
which may have come as a vector of factor letter combinations or a vector of column numbers in Yates order,
estimable.check
determines a list including elements estimable
,
a 2-row-matrix indicating estimable 2fis from the permissible inputs, and nfac
,
the number of factors from input parameter estimable
,
function estimable
calculates the appropriate design if certain effects have been requested to be estimable, and
all subsequent functions are auxiliary functions to function estimable
.
Yates
is a user-visible constant (cf. details section).
This package is still under development, but does already provide useful and well-tested results.
