R and Python Transform Support

R and Python connectivity and transforms occur over TCP/IP network links.

• For R, Rserve is used.
• For Python, FastAPI is the recommended integration method for Linux systems, while Pyro4 (Python Remote Data Objects) can be used on either Windows or Linux.

 

 

R Integration

1. Download R, install it, and the R Console ( http://cran.rstudio.com/ )
2. Open the R Console.
3. Install Rserve using the following command from within the R Console:

   install.packages("Rserve")

4. Initiatiate the Rserve library using the following command:

   library(Rserve)

5. Run Rserve by executing the following command:

   Rserve()

 

Only steps 2, 4 & 5 need to be repeated when R connectivity is required.

Example:

 

NOTE: Connectivity by default is over Port 6311.

 

 

To enable authentication across the Rserve TCP/IP link:

• Create a password file (pwdfile.pwd)

  Each line of the file should have the user and then the password.

  Example:

  user1 password1
  user2 password2

• Create a configuration file with following parameters (rconfig.conf)

  auth required
  pwdfile [path of password file]   

  Example:

  remote enable
  auth required
  port 6311
  pwdfile C:\\RIntegration\\pwdfile.pwd

• Load the created configuration file (the default Rserve configuration file is still loaded, but its settings have lower priority) and run Rserve:

  Rserve(args="--RS-conf [path of configuration file]")

  Example:

  Rserve(args="--RS-conf C:\\RIntegration\\rconfig.conf")
