# Functions Not Available in Spotfire Enterprise Runtime for R

With each release, Spotfire® Enterprise Runtime for R ( a/k/a TERR™) strives for compatibility with open-source R. In version 6.1, we tested functionality against open-source R version 4.2. At this time, the functions and methods listed in this document are available in open-source R, but are not currently available in TERR™.

The functions are listed alphabetically, according to their packages. The statistics package is further categorized by types of functions.

- base
- utils
- methods
- statistics

This table provides information about the numbers of functions implemented in open-source R that are also available in Spotfire Enterprise Runtime for R.

*Because TERR is included with Spotfire, most of the functions related to directly producing graphics are not supported; however, TERR contains placeholders for many graphics functions for package compatibility purposes.

Note: If you want to use the graphics functions available in R, you can use the `RGraph` function in the RinR package to generate graphics by passing an expression to open-source R and evaluating it there. You can also use a number of packages that use Javascript and htmlwidgets to create browser-based graphics. For more information, see Graphics in Spotfire Enterprise Runtime for R.
