Running the package requires R with the package rJava installed. Also requires Java 1.8 or higher.
See the instructions here for configuring your R environment, including Java.
To install the latest stable version, install from CRAN:
To download and use the JDBC drivers for BigQuery, Impala, or Netezza, see these instructions.
To be able to use Windows authentication for SQL Server, you have to install the JDBC driver. Download the .exe from Microsoft and run it, thereby extracting its contents to a folder. In the extracted folder you will find the file sqljdbc_4.0/enu/auth/x64/sqljdbc_auth.dll (64-bits) or sqljdbc_4.0/enu/auth/x86/sqljdbc_auth.dll (32-bits), which needs to be moved to location on the system path, for example to c:/windows/system32. If you not have write access to any folder in the system path, you can also specify the path to the folder containing the dll by setting the environmental variable
PATH_TO_AUTH_DLL, so for example
Sys.setenv("PATH_TO_AUTH_DLL" = "c:/temp").
