Execute a Cypher query and return a data frame

Convenience wrapper around lb_execute() that immediately converts the result to an R data.frame. Equivalent to as.data.frame(lb_execute(conn, query, ...)).

Usage

lb_query(conn, query, parameters = NULL, ...)

Arguments

conn

An lb_connection object from lb_connection().

query

A single character string containing a Cypher query.

parameters

A named list of query parameters for parameterised queries. NULL (default) means no parameters.

...

Passed to as.data.frame.lb_result().

Value

A data.frame.

Examples

if (FALSE) { # \dontrun{
db   <- lb_database(":memory:")
conn <- lb_connection(db)
lb_execute(conn, "CREATE NODE TABLE Person (name STRING, age INT64, PRIMARY KEY(name))")
lb_execute(conn, "CREATE (:Person {name: 'Alice', age: 30})")
df <- lb_query(conn, "MATCH (p:Person) RETURN p.name, p.age")
} # }
