I’m not sure how I missed this package, but I am sure glad I’ve found it. The `data.table`

package for **R** provides something of a reconceptualization of the standard `data.frame`

object. Though it remains (mostly) compatible with `data.frame`

. The advantage of `data.table`

is how it treats tables as if they were tables in a database. This allows extremely fast and intuitive merging of tables. Subsetting and summarizing tables are likewise much quicker. So, if you often find yourself dealing with large `data.frames`

that need merged, subsetted, and and summarized, I encourage you to take a look at `data.table`

. The R CRAN page and R-Forge development site are linked below.
