In biganalytics: A library of utilities for big.matrix objects of package bigmemory.

Description

This package extends the bigmemory package with various analytics. In addition to the more obvious summary statistics (see colmean, etc...), biganalytics offers biglm.big.matrix, bigglm.big.matrix, bigkmeans, binit, and apply for big.matrix objects. Some of the functions may be used with native R objects, as well, providing gains in speed and memory-efficiency.

Examples

# Our examples are all trivial in size, rather than burning huge amounts
# of memory simply to demonstrate the package functionality.

  dimnames=list(NULL, c("alpha", "beta")))
x
x[,]
x[,1] <- 1:5
