@rbjanis5 Yes to bookdown! I gave an #rladies presentation on all the things I'd figured out related to dissertating with rmarkdown and bookdown this time last year, which may or may not be useful: https://t.co/yJ1NuPD0O9

You're inevitably going to have to update to R 4.0.0 soon and as a result, you'll lose most of your packages and have to reinstall them. Here's a short script to keep a list of your current R packages and how to reinstall them after updating #rstats #statstwitter

A new report from @CurtinUni, @acereduau and @NCSEHE has investigated the feasibility of developing a student equity ranking system that could be used to inform performance-based funding. Here we present four different rankings based on the same measures. https://t.co/FVZwTmYKzV

@jelena3121 Sounds great. Look forward to your future work.

[Liang C. Zhang @LiangCZhang]

@jelena3121 Is this your PhD project? If it is, you could do some empirical work by collecting data like the one I suggest and build your own model. This way might generate more interesting stuff and get more opp to publish.

[Liang C. Zhang @LiangCZhang]

@jelena3121 This paper might further strengthen the empirical part of university ranking for your paper future work.https://t.co/PLhtJ9dK38
