R | data.table
data.table
is a fast and memory-efficient tabular data structure in the R collection of the same name. It performs much better in speed and memory usage than data.frame
or tibble
, and thus is useful for when doing work on large tables. The definition of "large" varies depending on the machine the table is being analyzed on, but typically it's the size at which the speed and memory usage of code involving the table become important considerations.
Note that data.table
uses different data grammar than what's present in the popular dplyr
package, as it is not part of the Tidyverse.
