x |
an object from the ' |
The First- and Last Letter Laws of the semigroup of relations correspond to the right and left zero of the semigroup, and it has some consequences in the interpretation of the results of the relational structure of the network. This function depends on the semigroup of a (recommended) labeled set of relationships.
S |
the semigroup of relations. |
strings |
the strings of relations in the semigroup. |
First.Letter |
the First.Letters in rows and columns |
Last.Letter |

Since this function is based on the semigroup construction, see the Warning section and look at other details in the semigroup
function section.

## Create the data: 3 binary relations among 3 elements
arr <- round( replace( array(runif(27), c(3,3,3)), array(runif(27),
c(3,3,3))>.75, 1 ) )
## Put labels
dimnames(arr)[[3]] <- list("n","m","ñ")
## Construct the semigroup
