full.ct | R Documentation |

The function `full.ct`

generates a `configTable`

with all (or a specified number of) logically possible value configurations of the factors defined in the input `x`

. It is more flexible than `allCombs`

.
`x`

can be a `configTable`

, a data frame, an integer, a list specifying the factors' value ranges, or a character string expressing a condition featuring all admissible factor values.

```
full.ct(x, ...)
## Default S3 method:
full.ct(x, type = "auto", cond = NULL, nmax = NULL, ...)
## S3 method for class 'configTable'
full.ct(x, cond = NULL, nmax = NULL, ...)
## S3 method for class 'cti'
full.ct(x, cond = NULL, nmax = NULL, ...)
```

`full.ct`

generates all or `nmax`

logically possible value configurations of the factors defined in `x`

, which can either be a character vector or an integer or a list or a data frame or a matrix.

If

`x`

is a character vector, it can be a condition of any of the three types of conditions,*boolean*,*atomic*or*complex*(see`condition`

).`x`

must contain at least one factor. Factor names and admissible values are guessed from the Boolean formulas. If`x`

contains multi-value factors, only those values are considered admissible that are explicitly contained in`x`

. Accordingly, in case of multi-value factors,`full.ct`

should be given the relevant factor definitions by means of a list (see below).If

`x`

is an integer, the output is a configuration table of type`"cs"`

with`x`

factors. If`x <= 26`

, the first`x`

capital letters of the alphabet are used as the names of the factors. If`x > 26`

, factors are named "X1" to "Xx".If

`x`

is a list,`x`

is expected to have named elements each of which provides the factor names with corresponding vectors enumerating their admissible values (i.e. their value ranges). These values must be non-negative integers.If

`x`

is a`configTable`

, data frame, or matrix,`colnames(x)`

are interpreted as factor names and the rows as enumerating the admissible values (i.e. as value ranges). If`x`

is a data frame or a matrix,`x`

is first converted to a`configTable`

(the function`configTable`

is called with`type`

as specified in`full.ct`

), and the`configTable`

method of`full.ct`

is then applied to the result. The`configTable`

method uses all factors and factor values occurring in the`configTable`

. If`x`

is of type`"fs"`

, 0 and 1 are taken as the admissible values.

The computational demand of generating all logically possible configurations increases exponentially with the number of factors in `x`

. In order to get an output in reasonable time, even when `x`

features more than about 15 factors, the argument `nmax`

allows for specifying a maximal number of configurations to be returned (by random sampling).

If not all factors specified in `x`

are of interest but only those in a given msc, asf, or csf, `full.ct`

can be correspondingly restricted via the argument `cond`

. For instance, `full.ct(d.educate, cond = "D + L <-> E")`

generates the logically possible value configurations of the factors in the set {D, L, E}, even though `d.educate`

contains further factors. The argument `cond`

is primarily used internally to speed up the execution of various functions in case of high-dimensional data.

The main area of application of `full.ct`

is data simulation in the context of inverse search trials benchmarking the output of `cna`

(see examples below). While `full.ct`

generates the relevant space of logically possible configurations of the factors in an analyzed factor set, `selectCases`

selects those configurations from this space that are compatible with a given data generating causal structure (i.e. the ground truth), that is, it selects the empirically possible configurations.

The method for class "cti" is for internal use only.

A `configTable`

of type `"cs"`

or `"mv"`

with the full enumeration of combinations of the factor values.
