10 packages on CRAN

itertools

cran
99.99th

Percentile

Various tools for creating iterators, many patterned after functions in the Python itertools module, and others patterned after functions in the 'snow' package.

doMPI

cran
99.99th

Percentile

Provides a parallel backend for the %dopar% function using the Rmpi package.

caret

cran
99.99th

Percentile

Misc functions for training and plotting classification and regression models.

foreach

cran
99.99th

Percentile

Support for the foreach looping construct. Foreach is an idiom that allows for iterating over elements in a collection, without the use of an explicit loop counter. This package in particular is intended to be used for its return value, rather than for its side effects. In that sense, it is similar to the standard lapply function, but doesn't require the evaluation of a function. Using foreach without side effects also facilitates executing the loop in parallel.

partDSA

cran
99.99th

Percentile

A novel tool for generating a piecewise constant estimation list of increasingly complex predictors based on an intensive and comprehensive search over the entire covariate space.

C50

cran
99.99th

Percentile

C5.0 decision trees and rule-based models for pattern recognition that extend the work of Quinlan (1993, ISBN:1-55860-238-0).

Cubist

cran
99.99th

Percentile

Regression modeling using rules with added instance-based corrections.

doMC

cran
99.99th

Percentile

Provides a parallel backend for the %dopar% function using the multicore functionality of the parallel package.

doParallel

cran
99.99th

Percentile

Provides a parallel backend for the %dopar% function using the parallel package.

iterators

cran
99.99th

Percentile

Support for iterators, which allow a programmer to traverse through all the elements of a vector, list, or other collection of data.
