Research direction

Start in data.table.R by locating all four fsort references, including the as.integer(fsort(as.numeric(irows))) call, and compare them with forder now that it is parallel. Review the existing nocov annotation and determine the appropriate change for each reference. Done means all four call sites have been revisited and the package checks pass.

Written by the indexing model from the issue text.

Description

internals

I had this one in mind :

as.integer(fsort(as.numeric(irows))) # nocov; parallelized for numeric but overhead of type conversion

Can revert to forder now that's parallel. Odd that the line is marked as # nocov.

There are 3 other references to fsort in data.table.R to revisit too.
