R Markdown and data validation are both really great things. Why not have them both together?! New in #rstats {pointblank} is a workflow that allows for nice and easy data validation in reproducible documents. Many more details here: https://t.co/jkmLzk0IHx. pic.twitter.com/E60e4SqR87

Recurring gripe: every so often I check citations on my #rstats packages. Results are always appalling (e.g. {ecmwfr} 11K downloads, 0 citations). So, I'll stress this again until researchers get it in their thick skull. Properly cite the software you use! #AcademicTwitter 1/ pic.twitter.com/iZGtjgvLF5
