ellipse

cran
99.99th

Percentile

Contains various routines for drawing ellipses and ellipse-like confidence regions, implementing the plots described in Murdoch and Chow (1996), A graphical display of large correlation matrices, The American Statistician 50, 178-180. There are also routines implementing the profile plots described in Bates and Watts (1988), Nonlinear Regression Analysis and its Applications.

orientlib

cran
99.99th

Percentile

Representations, conversions and display of orientation SO(3) data. See the orientlib help topic for details.

patchDVI

cran
99.99th

Percentile

Functions to patch specials in .dvi files, or entries in .synctex files. Works with "concordance=TRUE" in Sweave or knitr to link sources to previews.

rgl

cran
99.99th

Percentile

Provides medium to high level functions for 3D interactive graphics, including functions modelled on base graphics (plot3d(), etc.) as well as functions for constructing representations of geometric objects (cube3d(), etc.). Output may be on screen using OpenGL, or to various standard 3D file formats including WebGL, PLY, OBJ, STL as well as 2D image formats, including PNG, Postscript, SVG, PGF.

rglwidget

cran
99.99th

Percentile

The contents of this package have been merged into rgl, so it is no longer needed.

tables

cran
99.99th

Percentile

Computes and displays complex tables of summary statistics. Output may be in LaTeX, HTML, plain text, or an R matrix for further processing.

tkrgl

cran
99.99th

Percentile

Provides 'TK' widget tools for the 'rgl' package.

BrailleR

cran
99.99th

Percentile

Blind users do not have access to the graphical output from R without printing the content of graphics windows to an embosser of some kind. This is not as immediate as is required for efficient access to statistical output. The functions here are created so that blind people can make even better use of R. This includes the text descriptions of graphs, convenience functions to replace the functionality offered in many GUI front ends, and experimental functionality for optimising graphical content to prepare it for embossing as tactile images.

car

cran
99.99th

Percentile

Functions to Accompany J. Fox and S. Weisberg, An R Companion to Applied Regression, Third Edition, Sage, in press.

fortunes

cran
99.99th

Percentile

A collection of fortunes from the R community.

gsl

cran
99.99th

Percentile

An R wrapper for some of the functionality of the Gnu Scientific Library.

inline

cran
99.99th

Percentile

Functionality to dynamically define R functions and S4 methods with 'inlined' C, C++ or Fortran code supporting the .C and .Call calling conventions.

kableExtra

cran
99.99th

Percentile

Build complex HTML or 'LaTeX' tables using 'kable()' from 'knitr' and the piping syntax from 'magrittr'. Function 'kable()' is a light weight table generator coming from 'knitr'. This package simplifies the way to manipulate the HTML or 'LaTeX' codes generated by 'kable()' and allows users to construct complex tables and customize styles using a readable syntax.

knitr

cran
99.99th

Percentile

Provides a general-purpose tool for dynamic report generation in R using Literate Programming techniques.

99.99th

Percentile

Like package 'manipulate' does for static graphics, this package helps to easily add controls like sliders, pickers, checkboxes, etc. that can be used to modify the input data or the parameters of an interactive chart created with package 'htmlwidgets'.

nlsr

cran
99.99th

Percentile

Provides tools for working with nonlinear least squares problems. It is intended to eventually supersede the 'nls()' function in the R distribution. For example, 'nls()' specifically does NOT deal with small or zero residual problems as its Gauss-Newton method frequently stops with 'singular gradient' messages. 'nlsr' is based on the now-deprecated package 'nlmrt', and has refactored functions and R-language symbolic derivative features.

Rcmdr

cran
99.99th

Percentile

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

99.99th

Percentile

Edge-corrected kernel density estimation and binary kernel regression estimation for multivariate spatial point process data. For details, see Diggle, P.J., Zheng, P. and Durr, P. A. (2005) <doi:10.1111/j.1467-9876.2005.05373.x>.

vcdExtra

cran
99.99th

Percentile

Provides additional data sets, methods and documentation to complement the 'vcd' package for Visualizing Categorical Data and the 'gnm' package for Generalized Nonlinear Models. In particular, 'vcdExtra' extends mosaic, assoc and sieve plots from 'vcd' to handle 'glm()' and 'gnm()' models and adds a 3D version in 'mosaic3d'. Additionally, methods are provided for comparing and visualizing lists of 'glm' and 'loglm' objects. This package is now a support package for the book, "Discrete Data Analysis with R" by Michael Friendly and David Meyer.
