OrientR is a REST API wrapper for OrientDB. It allows you to run queries on OrientDB over its REST interface.

Install

install.packages("devtools")
devtools::install_github("retrography/OrientR")

Use

Load the library

library(OrientR)

Generate connection string

db <- getDB(database = "OpenBeer", host = "localhost", username = "root", password = "orientdb", port = "2480")

Run a query

query <- "SELECT FROM Beer"
resultSet <- runQuery(db, 'SELECT @rid AS id, name AS beer, out_HasBrewery.in.name AS brewery FROM Beer UNWIND brewery', batch = 100)

Note: It has come to my attention that OrientR fails to parse the data types for queries using the * selector (or equivalent). This is a known error now, but unfortunately I don't have the time to debug it. Feel free to make a pull request.

Known Issues

• Only Query function has been implemented in this preliminary version (see OrientDB's REST API manual for a list of possible extensions).
