In battmanux/swiplr: Interface SWI-Prolog from R

library(swiplr)

Some ideas for good usage

```{prolog database}

label(, header(1), "fr-FR", "Colonne une"). label(, row(1), "fr-FR", "Ligne une"). label(_, root, "fr-FR", "Document principale").

tr(Code, Fr) :- (label(, Code, "fr-FR", Fr) -> label(, Code, "fr-FR", Fr) ; Code = Fr ) .

cell_fr(Quoi, Entete, Ligne, Valeur) :- cell(What_, Header_, Row_, Value_), tr(What_, Quoi), tr(Header_, Entete), tr(Row_, Ligne), tr(Value_, Valeur) .

cell(root, header(1), row(1), 44). cell(root, header(12), row(25), 55). cell(root, header(10), row(1), 44). cell(root, header(10), row(25), 55). cell(root, header(4), row(1), 44). cell(root, header(10), row(5), 55).

?- cell(What, Header, Row, Value) ?- cell_fr(What, Header, Row, Value) ?- cell(What_, Header_, Row_, Value_), tr(What_, Quoi), tr(Header_, Entete), tr(Row_, Ligne), tr(Value_, Valeur)

```r
swiplr::table_query(.swiplr_chunks$database, 
                    query = "cell_fr(root, COLUMN_HEADER, ENTITY, CELL)")
