Research direction
Review the linked Stack Overflow discussion and the r-devel thread first; the issue names no file, test, or entry point in data.table. Done would mean agreeing on a psum? design, adding it for data.table users on R 3.1.0, and submitting the proposal to R-core.
Written by the indexing model from the issue text.
Description
Could add to data.table and submit to R-core too at the same time. This way psum is available to data.table users back to R 3.1.0 and we can remove from data.table when R dependency reaches if and when it's added to R.

Note that it hit resistance when I raised it on r-devel.
