RSnowflake

This R package extends dplyr to add backend support for SnowflakeDB. More details on dplyr can be found in the README page for the project.

This code was originally forked from snowflakedb/dplyr-snowflakedb. In order to accept issues and pull requests, I created this repo.

R Environment Setup

The dplyr.snowflakedb connectivity to SnowflakeDB uses the RJDBC package, however, the rJava package needs to be installed and working with Java 8 to support the SnowflakeDB JDBC requirements. This may require:

  • installing Java 8
  • running R CMD javareconf so R uses the Java 8 for its JAVA_HOME
  • installing rJava from source so it can be linked against Java 8

If you are using R on Mac OS X, please see this wiki page for the necessary installation steps for rJava.

Once you have rJava installed and verified it is using Java 8, you can install dplyr and dependancies.

install.packages(c("RJDBC", "DBI", "dplyr"))

If you'd like some data to experiment with I'd recommend installing the following packages that most of the dplyr examples and vignettes use.

install.packages(c("nycflights13", "Lahman"))

Installing dplyr.snowflakedb

install.packages("devtools")
devtools::install_github("zacharyrsmith/RSnowflake")

Example SnowflakeDB Connection

library(dplyr)
library(dplyr.snowflakedb)
options(dplyr.jdbc.classpath = "/home/snowman/Downloads/snowflake_jdbc.jar")

my_db <- src_snowflakedb(user = "snowman",
                         password = "letitsnow",
                         account = "acme",
                         opts = list(warehouse = "mywh",
                                     db = "mydb",
                                     schema = "public"))
