Description

Functions to select elements or extract information from design catalogues of class catlg

Usage

res.catlg(catlg)
nruns.catlg(catlg)
nfac.catlg(catlg)
WLP.catlg(catlg)
nfree.2fis.catlg(catlg)
free.2fis.catlg(catlg)
all.2fis.free.catlg(catlg)
catlg
## S3 method for class 'catlg':
catlg[i]

Arguments

catlg Catalogue of designs of class catlg (cf. details section)
i vector of index positions or logical vector that can be used for indexing a catlg object

Details

The class catlg is a named list of design entries, currently containing the Chen, Sun and Wu (1993) 2-level designs only (complete list of 2-level fractional factorials up to 32~runs, complete list of resolution IV 2-level fractional factorials with 64~runs). Each design entry is again a list with the following items:

Reference to factors in components nfree.2fis and all.2fis.free is via their position number (element of (1:nfac)).

Value

[ selects a subset of designs based on i, which is again a list of class catlg, even if a single element is selected. res, nruns, nfac and nfree.2fis return a named vector, the remaining functions return a list.
