HeavyDB supports the R language using RJDBC.

Examples

Local Host Example

library(RJDBC)
drv <- JDBC("com.heavyai.jdbc.HeavyAIDriver",
            "/home/heavyai/bin/heavyai-utility-6.0.jar",
            identifier.quote="'")
conn <- dbConnect(drv, "jdbc:heavyai:localhost:6274:heavyai", "admin", "HyperInteractive")
dbGetQuery(conn, "SELECT i1 FROM test1  LIMIT 11")
dbGetQuery(conn, "SELECT dep_timestamp FROM flights_2008_10k  LIMIT 11")

Remote Host Example

library(RJDBC)
drv <- JDBC("com.heavyai.jdbc.HeavyAIDriver",
            "/home/heavyai/bin/heavyai-utility-6.0.jar",
            identifier.quote="'")
conn <- dbConnect(drv,
                  "jdbc:heavyai:colossus.heavyai.com:6274:heavyai",
                  "admin",
                  "HyperInteractive")
dbGetQuery(conn,
  paste("SELECT date_trunc(month, taxi_weather_tracts_factual.pickup_datetime)",
        "  as key0,",
        "AVG(CASE WHEN 'Hyatt' = ANY",
        "    taxi_weather_tracts_factual.dropoff_store_chains THEN 1 ELSE 0 END)",
        "  AS series_1",
