99th

Percentile

Plots a three dimensional (3D) point cloud.

nortest

cran
98th

Percentile

Five omnibus tests for testing the composite hypothesis of normality.

klaR

cran
98th

Percentile

Miscellaneous functions for classification and visualization, e.g. regularized discriminant analysis, sknn() kernel-density naive Bayes, an interface to 'svmlight' and stepclass() wrapper variable selection for supervised classification, partimat() visualization of classification rules and shardsplot() of cluster results as well as kmodes() clustering for categorical data, corclust() variable clustering, variable extraction from different variable clustering models and weight of evidence preprocessing.

signal

cran
97th

Percentile

A set of signal processing functions originally written for 'Matlab' and 'Octave'. Includes filter generation utilities, filtering functions, resampling routines, and visualization of filter models. It also includes interpolation functions.

R2WinBUGS

cran
96th

Percentile

Invoke a 'BUGS' model in 'OpenBUGS' or 'WinBUGS', a class "bugs" for 'BUGS' results and functions to work with that class. Function write.model() allows a 'BUGS' model file to be written. The class and auxiliary functions could be used with other MCMC programs, including 'JAGS'.

tuneR

cran
94th

Percentile

Analyze music and speech, extract features like MFCCs, handle wave files and their representation in various ways, read mp3, read midi, perform steps of a transcription, ... Also contains functions ported from the 'rastamat' 'Matlab' package.

BRugs

cran
94th

Percentile

Fully-interactive R interface to the 'OpenBUGS' software for Bayesian analysis using MCMC sampling. Runs natively and stably in 32-bit R under Windows. Versions running on Linux and on 64-bit R under Windows are in "beta" status and less efficient.

fftw

cran
92th

Percentile

Provides a simple and efficient wrapper around the fastest Fourier transform in the west (FFTW) library <http://www.fftw.org/>.

RWinEdt

cran
49th

Percentile

A plug in for using 'WinEdt' as an editor for R.

xtable

cran
99.9th

Percentile

Coerce data to LaTeX and HTML tables.

dendextend

cran
99th

Percentile

Offers a set of functions for extending 'dendrogram' objects in R, letting you visualize and compare trees of 'hierarchical clusterings'. You can (1) Adjust a tree's graphical parameters - the color, size, type, etc of its branches, nodes and labels. (2) Visually and statistically compare different 'dendrograms' to one another.

Rcmdr

cran
98th

Percentile

A platform-independent basic-statistics GUI (graphical user interface) for R, based on the tcltk package.

fortunes

cran
94th

Percentile

A collection of fortunes from the R community.

R2OpenBUGS

cran
91th

Percentile

Using this package, it is possible to call a BUGS model, summarize inferences and convergence in a table and graph, and save the simulations in arrays for easy access in R.

reliaR

cran
88th

Percentile

A collection of utilities for some reliability models/probability distributions.

RobPer

cran
85th

Percentile

Calculates periodograms based on (robustly) fitting periodic functions to light curves (irregularly observed time series, possibly with measurement accuracies, occurring in astroparticle physics). Three main functions are included: RobPer() calculates the periodogram. Outlying periodogram bars (indicating a period) can be detected with betaCvMfit(). Artificial light curves can be generated using the function tsgen(). For more details see the corresponding article: Thieler, Fried and Rathjens (2016), Journal of Statistical Software 69(9), 1-36, <doi:10.18637/jss.v069.i09>.
