What is broman?

A statistician's personal toolbox, growing one plotting utility at a time

broman is Karl Broman's collection of personal R utilities — base-graphics plotting helpers such as grayplot, dotplot and timeplot, running-window summaries, and assorted conveniences. Recent releases alternate between small additions, like runningratio2() with an adaptive window sized to hit a target denominator, and narrow bug fixes in crayons() and jiggle(). Version 0.92 removes an include that had begun warning on CRAN.

What is Chord?

Chord's assistant can now write to the team's knowledge base, not just read from it.

Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.

◆ Current state

broman is Karl Broman's collection of personal R utilities — base-graphics plotting helpers such as grayplot, dotplot and timeplot, running-window summaries, and assorted conveniences. Recent releases alternate between small additions, like runningratio2() with an adaptive window sized to hit a target denominator, and narrow bug fixes in crayons() and jiggle(). Version 0.92 removes an include that had begun warning on CRAN.

◆ Where it's heading

The additions cluster around two themes: time-axis plotting and running-window summaries, both of which have been extended across several releases. Nothing here is planned in the usual sense — functions appear when the author needs them and bugs are fixed when they surface downstream, as jiggle() did through dotplot(). The C-level cleanup in 0.92 matches the same change made to R/qtl the same week, which is what maintaining a set of packages under one author looks like.

◆ Prediction

Both recent function additions extend existing families rather than starting new ones, so the next release is most likely another variant in the running-window or time-plotting group, or a fix surfaced by one of the author's other packages.

Chord's assistant can now write to the team's knowledge base, not just read from it.

◆ Current state

Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.

◆ Where it's heading

The arc runs from answering questions to acting and now to accumulating. Each release has closed one gap in that loop — answers that show their reasoning, then grounding in the customer's definitions, then feedback capture, then building audiences directly, and now retaining what it learns for the whole team. The rename from Copilot signals the assistant is being treated as the product surface rather than an add-on to it. Release notes arrive on a strict two-week cadence and the feed truncates their bodies, so specifics beyond the headline features are not visible.

◆ Prediction

Acting on that accumulated memory is the natural next step, since the assistant can already build audiences and now retains definitions across conversations.
