New release of the c14bazAAR #rstats package! c14bazAAR features a set of download functions for open #C14 date archives -- and now a new one for the machine-generated tegiszhol dataset (calgacus.srht.site). The package works as a quick and easy […] [Original post on archaeo.social]

Positioning text labels in scatter plots is not always easy with #ggplot2, even with clever extensions like ggrepel. A new release of my #rstats package ggpointgrid aims to add another string to our bow here. To show what I mean I wrote a little blog post with […] [Original post on archaeo.social]

A recent preprint by Shastry, Musiani & Novembre 2025 (doi.org/10.1101/2025.02.10.637386) includes a neat human genomic dataset: c1global1nfd_public. I was originally compiled for Peter, Petkova & Novembre 2020 (doi.org/10.1093/molbev/msz280) […] [Original post on archaeo.social]

I finally managed to fulfill my dream of using #futhark-lang (futhark-lang.org) in an #rstats package. v1.4.0 of my ggpointgrid package (github.com/nevrome/ggpointgrid) uses a futhark implementation of the core arrangement algorithm, transpiled […] [Original post on archaeo.social]

For the final talk "A command-line interface for chronological network modelling in R" Eythan Levy and Joe Roe (and Gilles Geeraerts) once more talked about an eDSL for age modelling. The #rstats package chronologr (github.com/joeroe/chronologr) is a […] [Original post on archaeo.social]

Back to the topic of web APIs, Jonathan Westin (and Matteo Tomasini, Tristan Bridge, and Aram Karimi) demonstrated how archaeological data can shine in the hands of a team of professional back- and front-end developers. The "Etruscan Chamber tombs Portal: a […] [Original post on archaeo.social]

In "Open-Source Bayesian Chronological Modeling: The Role of a Domain-Specific Language" Martin Hinz (and Joe Roe) shared ideas and a prototype implementation of an eDSL for probabilistic age modelling. Not unlike OxCal (c14.arch.ox.ac.uk/oxcal.html), but open source.

I had the honour of leading into the session with "Building a tree-walk interpreter - a didactic deep dive into the age modelling language of the currycarbon software tool". This talk was a plea to consider DSLs as useful software interfaces for archaeologists […] [Original post on archaeo.social]

Had an odd moment yesterday: I wrote some #rstats for 3D data visualisation and needed a function to rotate coordinates around a pivot point. When I googled I found some of my own code I had written seven years ago. I had totally forgotten about that 😄. It did […] [Original post on archaeo.social]

currycarbon v0.4.0.0 is finally available. This version comes with a number of visible and invisible changes, most obviously an extension of the neat command line plot. This version is again available for MS Windows. github.com/nevrome/currycarbon #archaeology #Haskell #C14

I recently have started to casually work on another update for my #C14 calibration #Haskell library and command line tool currycarbon (github.com/nevrome/currycarbon). I would like to add a plot element that shows the calibration curve above the […] [Original post on archaeo.social]
