A review of data.table (1.5)

5

very useful

I found this package right after I was working with data frames large enough that many summaries were taking 30-60 seconds each. The use of data.table cut this down to about 1 second. I now consider using data.table for any large data problem--with time, I may use its nice syntax (e.g. very nature to plot a subset of the data concisely) for "everyday" use.
