Error 0063

This exception is raised when R script evaluation fails with an error.

This error occurs when you have provided an R script in one of the R language modules in Azure Machine Learning, and the R code contains internal syntax errors. The exception can also occur if you provide the wrong inputs to the R script.

The error can also occur if the script is too big to execute in the workspace. The maximum script size for the Execute R Script module is 1,000 lines or 32KB of work space, whichever is lesser.

1. In Azure Machine Learning Studio, right-click the module that has the error, and select View Log.
2. Examine the standard error log of the module, which contains the stack trace.
   • Lines beginning with [ModuleOutput] indicate output from R.
   • Messages from R marked as warnings typically do not cause the experiment to fail.
3. Resolve script issues.
   • Check for R syntax errors. Check for variables that are defined but never populated.
   • Review the input data and the script to determine if either the data or variables in the script use characters not supported by Azure Machine Learning.
   • Check whether all package dependencies are installed.
   • Check whether your code loads required libraries that are not loaded by default.
   • Check whether the required packages are the correct version.
   • Make sure that any dataset that you want to output is converted to a data frame.
4. Resubmit the experiment.
