# data.table: an R package everyone should use

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.
