R data.table

Getting back into R the past few weeks has been fun. My colleagues are fans of data.table, so I’ve been trying to wrap my brain around it’s terse but powerful syntax.

Resources on data.table:

• The data.table home page.

• The vignette Introduction to data.table.

• JOINing data in R using data.table

• Advanced tips and tricks with data.table.

• Frank Erickson’s Quick R Tutorial has a nice section on data.tables.

• A comparison with the Tidyverse tool set: data.table vs. dplyr in split-apply-combine style analysis.
