⎕CSV and ⌸
The key operator ( ⌸ ) is used to perform GROUP BY-style aggregations in Dyalog. In this workshop we explore ways to import and pre-process data, looking at the fastest formats for data analysis in the workspace. We investigate techniques for aggregating and inspecting large datasets, including methods for efficient and convenient computation on the grouped data, and walk you through analysing a real dataset using ⎕CSV and ⌸.
Assumed knowledge: Basic knowledge of Dyalog APL, high school mathematics. Knowledge of GROUP-BY is helpful but not essential. No prior knowledge of ⎕CSV and ⌸ is necessary.
DYNA Fall 2025 is an in-person only event. Registration is essential to ensure we can accommodate all attendees comfortably and plan appropriate refreshments. Please note that lunch and refreshments during breaks are included on both days, but evening meals and accommodation are not.
Day 1 presentations are free. Day 2 workshops cost $250. Join us for either day—or both!
