genChild | R Documentation |
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)
array.line |
a row from data frame |
array.list |
the output from function |
nbRuns |
the number of runs of the array to be received |
descr |
a character string containing the description of the array
to be retrieved, of the form |
name |
name of an array according to the naming conventions in
|
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.
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.
