R

Tristan Mahr explains what tibbles and tribbles are and how they compare to built-in data frames:

The name “tribble” is short for “transposed tibble” (the transposed part referring to change from column-wise creation in tibble() to row-wise creation in tribble()).

I like to use light-weight tribbles for two particular tasks:

  • Recoding: Create a tribble of, say, labels for a plot and join it onto a dataset.

  • Exclusion: Identify observations to exclude, and remove them with an anti-join.

I’ve been more used to data frames than tibbles, but this post shows some interesting things you can do with tibbles a lot more easily than with data frames.  It’s enough to make me want to use tibbles more frequently.  H/T R-bloggers
