Tableau R Classroom Training and Certification Classes

Tableau can be integrated with R by using calculated fields which invoke the R engine and pass values to R through the Rserve package. It is also possible to use tab admin utility for connecting Tableau Server with an Rserve instance which allows the view of R functionality dashboard.

• Using the ‘write.csv’ command within the calculated field
• Using the debug version of the standalone executable of Rserve (Rserve_d.exe)

By either output R images into Tableau dashboards as image objects or point to R images through URL objects.

Four new built-in functions are available:

• SCRIPT_REAL
• SCRIPT_STR
• SCRIPT_INT
• SCRIPT_BOOL

The following core capabilities of R cannot be utilized directly in Tableau:

• The data cannot be directly exported from Tableau into R to run a new model outside of using the SCRIPT_* functions.
• The visualizations created in R also cannot be imported into Tableau directly.
• Datasets cannot be imported into Tableau from R
