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.
