We present fplyr, a new package for the R language to deal with big files. It allows users to easily implement the split-apply-combine strategy for files that are too big to fit into the available memory, without relying on data bases nor introducing non-native R classes. A custom function can be applied independently to each group of observations, and the results may be either returned or directly printed to one or more output files.

The Split-Apply-Combine Strategy for Data Analysis
This paper gives rise to a new R package that allows you to smoothly apply a split-apply-combine strategy, without having to worry about the type of structure in which your data is stored. Expand
Scalable Strategies for Computing with Massive Data
Two complementary statistical computing frameworks that address challenges in parallel processing and the analysis of massive data can be used in combination to address challenges that have effectively been beyond the reach of researchers who lack specialized software development skills or expensive hardware.

Reshaping Data with the reshape Package
The reshape package for R is presented, which provides a common framework for many types of data reshaping and aggregation, where the data are ‘melted’ into a form which distinguishes measured and identifying variables, and then cast into a new shape, whether it be a data frame, list, or high dimensional array.

iotools: High-Performance I/O Tools for R
The iotools package provides a set of tools for Input/Output (I/O) intensive datasets processing in R which minimize copying and avoid the use of intermediate string representations whenever possible. Expand
