(ab)Using this feature I submitted the draft of a second abstract to #useR2026. Now I need a bit of conference-driven-development to fill it up well :D This one is about the recently opened up data from CRAN.

Given the ids to each abstract, I think there are around 6 submissions per week.

Anyone knows if is it possible to edit an abstract submission once sent to the #useR2026 conference? It uses the indico platform but I don't find any mention for this.

Just checking if I can submit now and edit as the conference-driven-analysis take shape. For now, the data is under review as it has some errors and will need to be generated again from its primary sources.

#rStats How should we submit tutorials or talks to @useR_conf ? I can't find any information about the structure or format we should use for #useR2026.

This time it might be the first time I present something from work. I'll probably also submit another talk for one project I've been working on.

In this keynote, Peter Dalgaard will take us back to R’s origins in the 1990s and trace how its development principles took shape alongside the PC, Internet, and Open-Source revolutions. From there, he’ll unpack how R Core approaches release management, and how governance is shared across the broader ecosystem, including the CRAN team, the R Foundation, and the R Consortium.
