aggregateR 1.5.1 (2026-10-19)

Fixed

  • The README and agg_start()'s failure message no longer say to wait for aggregate-api 1.26 on PyPI; it has been there since 1.26.1. A failed start now shows the end of the server's log and nothing else.

aggregateR 1.5.0 (2026-10-18)

Added

  • agg_start(port, from) runs aggregate-api through uvx on 127.0.0.1 and points the session at it; agg_stop() stops it and restores the previous server. Quitting R stops it too. processx is now imported.
  • Without uv, agg_start() gives the install line. Until aggregate-api 1.26 is on PyPI, it fails with uv's reason and asks for from, such as a git spec.
  • Measured on this machine: a cold start from git with an empty uv cache answered in 22 s, a warm start from a checkout in 6 s.

Changed

  • The first request to the public server now says agg_start() runs a private local server.

aggregateR 1.4.0 (2026-10-18)

Added

  • agg_library(database) lists the example library's entries, name and kind, in file order.
  • agg_program(name, database) returns an entry's DecL program as its file spells it, ready for agg_build(). An unknown name says so and points at agg_library().
  • The listing is fetched once per R session, server and database; a refused database is not kept.

aggregateR 1.3.0 (2026-10-18)

Added

  • agg_frames(x) lists an object's frames with their rows and columns.
  • agg_frame(x, which = "density_df") returns a whole frame as a plain data.frame. It reads Parquet through nanoparquet (now imported) when the server offers it, and CSV otherwise or on a 501.
  • Measured on a local server, a two-unit portfolio's density_df at log2 16 (65,536 by 33): Parquet 0.06 s, CSV 5.5 s. Finite values agree to 2.2e-16; gaps and infinities agree exactly.
  • The server's facts are fetched once per R session and server, for frame_formats.

aggregateR 1.2.0 (2026-10-18)

Added

  • agg_exhibits(x) lists an object's exhibits: name, title and perspectives.
  • agg_exhibit(x, name, perspective) returns an agg_exhibit, always a list: title, captions and tables, the last two named by the server's block keys (summary_df, reins_stats_df). Its print shows each block's caption and table.
  • Exhibit tables hold data only: row labels as character with spanned labels repeated, values as the server's raw numbers (NA where it has none), header levels joined into column names. They match the Excel add-in's spill cell for cell on its fixtures.
  • agg_q(x, p, basis) returns exact quantiles for p in [0, 1], named like quantile()'s.
  • Every function that takes x accepts a handle or a DecL program.

aggregateR 1.1.0 (2026-10-18)

Added

  • agg_build(decl, log2, bs) builds a program and returns an agg_handle, or the number a value program such as (2+2) means. A character vector joins into one program, so readLines() of a .agg file works.
  • The handle carries its recipe and server, prints its grid, moments and validation, and survives saveRDS() into a later R session.
  • A build memo: the same program on the same grid posts once per R session and server. Building a name to a new id (a redefinition) clears it.
  • A read through a handle whose object the server evicted rebuilds it and retries. If the rebuild gives a different id, the call is refused and asks for agg_build().
  • A program naming the session's own declarations (port P agg.A ...) survives a server restart: the client replays the missing declaration from its build log and retries.

aggregateR 1.0.0 (2026-10-18)

Added

  • The package: DESCRIPTION (BSD-3), the RStudio project, and testthat tests that need no server.
  • agg_server() gets or sets the server: the aggregateR.server option, then AGGREGATER_SERVER, then the public https://agg.mynl.com. The first request to the public server each R session says that programs are sent there.
  • agg_meta() returns the server's facts: versions, grid caps, cache size and frame formats.
  • Requests carry a per-server session id and retry a 429 up to three times, honoring Retry-After up to 60 s.
  • Failures raise aggregateR_refusal or aggregateR_transient, both inheriting aggregateR_error, with the Excel add-in's readable text.
