Two talks: {renv} for reproducibility & {rtables} for complex data tabulation

For this meetup we have two talks lined up. Times below are approximate. In-person participants are welcome to join speaker Gabe Becker and host Heather Turner for dinner/drinks afterwards at the Dirty Duck. **How to make {renv} actually work, Shannon Pileggi, 5:00 PM to 5:30 PM BST** The {renv} package aims to *help* users create reproducible environments for R projects. In theory, this is great! In practice, restoring a package environment can be a frustrating process due to overlooked R configuration requirements. Join me to better understand the source of environment restoration issues and learn strategies for successful maintenance of {renv}-backed projects. **rtables - A grammar for complex, multi-level data tabulations and analysis, Gabe Becker, 5:30 - 6:15 PM** Tables form a central component in both exploratory data analysis and formal reporting procedures across many industries. These tables are often complex in their conceptual structure and in the computations that generate their individual cell values. With {rtables}, we re-contextualize tables as a special case of the larger, well researched field of data visualization. We present a specialized, pipeable grammar for declaring table structure which maps to Wilkinson's Grammar of Graphics. This talk will be a blend of our conceptual research and practical examples of what the 'rtables' framework can do.
