Run R Scripts

R scripts can be executed like any other script (OML, Tcl, and Python) by pressing the Run button. Likewise, you can interrupt them by pressing the Stop button.

Run R Scripts

It is important to note how the R interpreter is accessed from Compose. When Compose starts, only the OML interpreter is loaded. The Python and R interpreters are only loaded “on demand”.

To access the R interpreter:
  1. Select File > New > R script OR File > Load and select an existing R script.
  2. By selecting an R script, the R interpreter (as defined by the R_HOME environment variable) is loaded and the R Command Window is displayed.
  3. Use the View menu to show or hide the R Command Window.
The following differences exist between the way Compose runs a script and the run in R:
  • The Run button in Compose works like “source” in R: it executes all commands, but silently.
  • Run Selection is available for all or part of the script.
  • To emulate the verbose run in the R environment, select all lines of the script and select Run Selection.
