I got the error message above. This issue has been reported before (https://github.com/Rdatatable/data.table/issues/2997) and seems to have been resolved.

Minimal reproducible example (from the previous github post): B <- CJ(i2 = letters, orig = runif(50)) B[, orig := as.character(orig)] B[, mergeKey := as.character(orig)] B[, .SD[1L], by = mergeKey]

@stephanpdx Thanks for the report, could you try to reproduce issue on recent development version, or at least on 1.13.2? AFAICT (and what also #2997 concludes) this issue has been resolved already and you just need to upgrade your data.table version.

Thanks Jan -- I'll ask the system administrator to upgrade. I think we can close this issue.
