It turns out that the SPLIT(), FINDNTH(), and REGEX... functions introduced in v9 do not support table calcs or fields from multiple data sources, here's an example:

I would like that support. The particular use case I have in mind is parsing out data returned from R scripts, it would be a lot easier if I had access to these features.

Also FLOOR() and CEILING() are not available for table calculations either.
