R Execute Error Messages

Because R Execute is an operator that executes the user's arbitrary code, many things can go wrong. The R Execute operator includes error messages to help you identify the source of the problem.

  • Syntax errors in the R script
    A common syntax mistake in an R script can result in an error when you run the R Execute operator.
  • Logical errors in the user's R script
    A logical mistake in an R script can result in an error when you run the R Execute operator.
  • Input data size limitations
    Pulling too much data can result in an error when you run the R Execute operator.
  • Output data size limitations
    If a returned dataset exceeds the allowed limit, R reports a size limit error.
  • Network issues
    A connection failure or a partition between nodes can result in a network error.
  • Missing output reference in the R script
    If the output properties in the R Execute Operator are set differently than that the script expects, an output error can occur.
  • Column name or type mismatches
    Column names, column types, and column count specified in the R Execute operator must match those returned by the R script.
  • Type coercion error
    R sometimes performs type coercion, which you might not expect. Type coercion can cause problems because the R Execute operator expects R to return a data frame if you assign the alpine_output variable in the R script.
