Converts a Java object returned by r5r_network to an R data.table

Usage

java_to_dt(obj, ids = NULL)

Arguments

obj

A Java Object reference

ids

An optional named list of character vectors, e.g. list(from_id = origins$id, to_id = destinations$id), holding the ids sent to Java. String columns named here are transferred as integer positions in these vectors, which is much faster than transferring one Java string per row.
