Release: jsplyr 0.2.0

[maciekbanas]

Overview

Tracking issue for the jsplyr 0.2.0 release. This is a backward-compatible feature expansion following the planned 0.1.1 patch. Full details in spec.md.

Scope: new verbs, the .by argument, the full tidyselect helper set in select(), expanded expression functions, and new aggregations. Bug issues #15 and #17 are out of scope.

New verbs

• Add transmute() verb #18 transmute()
• Add rename_with() verb #19 rename_with()
• Add slice_sample() verb #20 slice_sample()
• Add add_count() and add_tally() verbs #21 add_count() / add_tally()
• Add reframe() verb #22 reframe()

Other release work (from spec.md)

• Column-name tracking foundation on tbl_lazy_json (unblocks tidyselect helpers and negation)
• .by argument for mutate(), summarise(), slice*(), reframe()
• select() tidyselect helpers: starts_with, ends_with, contains, matches, everything, last_col, where, negation (-col)
• Expression functions (mutate/filter): string ops, math ops, %in%, coalesce, na_if
• Aggregations: n_distinct, first, last, var, nth
