A new {rrapply} 📦-version is available on #cran: a minimal (dependency-free) revisit of rapply() for efficient recursion through nested lists and expressions in #rstats.

@MajeedOlaide @OpenAnalytics Hi Majeed, here is a gist containing the relevant R-code to reproduce the graph (in ggplot2): https://t.co/RieUPe8nuG

This week's #TidyTuesday on #Eurovision: Country biases in televoting ☎️

Nordic countries consistently award extra points to their closest neighbors. Balkan countries are generally not big fans of the Nordics...

@WillBall12 Interesting! For nose-dives one could check for large negative first-order differences/derivatives. For e.g. double peaks I guess you could remove the global/mean trends and then check for specific local artifact structures in the residual time series

Highlighting several baby names with short peak popularity throughout US history.

My personal favorites:

@richard_vogg Thanks! I took second-order differences of all time series and then looked for the names with a maximum absolute value that was very large relative to the standard deviation (of the second-order differences).
