The functions are used internally for creating the child arrays listed in
data frame oacat from the parent arrays that come with DoE.base
(or using full factorials).
parseArrayLine(array.line)
genChild(array.list)
getArray(nbRuns, descr)
symb2oa(nbRuns, descr)
oa2symb(name)parseArrayLine returns a list with design and lineage description in symbolic form.
genChild and getArray return an array matrix of class oa.
symb2oa and oa2symb return a character string.
a row from data frame oacat
the output from function parseArrayLine
the number of runs of the array to be received
a character string containing the description of the array
to be retrieved, of the form
nl1~fl1;nl2~fl2; ..., where nl stands for the number of levels
and fl for their respective frequency; the string may (but need not)
contain a trailing semicolon
name of an array according to the naming conventions in
oacat

Function parseArrayLine transforms information from a row of oacat
into a list format digestible by function genChild.
Function genChild creates a child array from the appropriate information
provided by function parseArrayLine.
Function getArray retrieves a stored orthogonal array based on the list
information it receives.
Functions symb2oa and oa2symb can be used for
switching between design names from data frame oacat
and list type information used by functions internally. Note that the result
from oa2symb is not sufficient to get back to the oa representation,
but needs the number of runs in addition.
