In this video training Jared starts with some common data manipulation operations using various base R functions and packages like plyr, comparing the speed of in memory calculations.

He then demonstrates more advanced techniques for accomplishing the same task such as data.table, dplyr, Rcpp and parallel computation for increased speed. Finally, for when data size is an even bigger factor than speed he introduces external memory and database techniques using bibmemory, ff, SciDB, dplyr and Hadoop.
