Enhanced R Script

Enhanced R Script

EnhancedRScript.py is a Python script intended as an easy interface between the Discovery Environment and R scripts. The Python command line can be used to modify a specially-designed R script before executing that modified R script.

EnhancedRScript scans an R script for any parameter names surrounded by two dollar signs on both sides, e.g, $$name$$ or $$myvar$$. Those parameter names can then be options on the EnhancedRScript command line, with the parameters replaced by command line options. For example, "$$name$$" would be replaced by the --name= option value on the EnhancedRscript command line. Defaults are also supported, and EnhancedRScript can also generate a script without executing it for debugging purposes. The Rscript command can, of course, pass parameters to an R script as well, but the Python wrapper is intended to provide more flexibility in some respects.

The basic Enhanced R Script application in the Discovery Environment is intended as a demonstration and can run scripts without the parameters as described above. To run scripts with replacement parameters, create a new Discovery Environment application. Examples include Linear Regression in R and Generalized Linear Regression in R.
