BotRNot: An R app to detect Twitter bots

Twitter's bot problem is well documented, influencing discourse on divisive topics like politics and civil rights. But it's getting harder and harder to spot such nefarious bots, who often borrow biographies and tweets from real (and often stolen) profiles to evade detection.

But you also need to “practice big” by working on larger projects. To get some practice, my recommendation is to find reasonably sized datasets online and plot them. The post How to...
