Packages

dataframe

This contains versions of standard data frame functions in R, modified to avoid making extra copies of inputs. This is faster, particularly for large data.

The current version is dataframe_2.7.1.tar.gz. This is for R 2.15.1 - 2.15.3. It includes changes made through R 2.15.3. This will not work with R 3.0.

This will not go on CRAN. New CRAN policies prohibit .Call calls to routines internal to R; these are present in some of the standard dataframe code.

An older version is below, dataframe_2.5.tar.gz. This is suitable for R 2.15.0. It can be used with earlier versions if you create paste0, like paste but default sep="", then edit DESCRIPTION to remove the dependence on R 2.15.0.

The file memory.R (see below) has some benchmarks, including R 3.0.0 (without the dataframe package). R 3.0.0 does more large memory allocations than previous versions. They are not copies of the data. Some people from r-devel are looking into this.

aggregate

Aggregation functions. Common aggregation tasks optimized for speed and ease of use.
