compare

cran
14th

Percentile

Functions to compare a model object to a comparison object. If the objects are not identical, the functions can be instructed to explore various modifications of the objects (e.g., sorting rows, dropping names) to see if the modified versions are identical.

graphicsQC

cran
14th

Percentile

Functions to generate graphics files, compare them with "model" files, and report the results, including visual and textual diffs of any differences.

gridBase

cran
14th

Percentile

Integration of base and grid graphics

gridDebug

cran
14th

Percentile

Functions for drawing scene trees representing scenes that have been drawn using grid graphics.

14th

Percentile

Functions to convert a page of plots drawn with the 'graphics' package into identical output drawn with the 'grid' package. The result looks like the original 'graphics'-based plot, but consists of 'grid' grobs and viewports that can then be manipulated with 'grid' functions (e.g., edit grobs and revisit viewports).

14th

Percentile

Functions for drawing node-and-edge graphs that have been laid out by graphviz. This provides an alternative rendering to that provided by the 'Rgraphviz' package, with two main advantages: the rendering provided by 'gridGraphviz' should be more similar to what 'graphviz' itself would draw; and rendering with 'grid' allows for post-hoc customisations using the named viewports and grobs that 'gridGraphviz' produces.

gridSVG

cran
14th

Percentile

Functions to export graphics drawn with package grid to SVG format. Additional functions provide access to SVG features that are not available in standard R graphics, such as hyperlinks, animation, filters, masks, clipping paths, and gradient and pattern fills.

grImport

cran
14th

Percentile

Functions for converting, importing, and drawing PostScript pictures in R plots.

grImport2

cran
14th

Percentile

Functions for importing external vector images and drawing them as part of 'R' plots. This package is different from the 'grImport' package because, where that package imports 'PostScript' format images, this package imports 'SVG' format images. Furthermore, this package imports a specific subset of 'SVG', so external images must be preprocessed using a package like 'rsvg' to produce 'SVG' that this package can import. 'SVG' features that are not supported by 'R' graphics, e.g., gradient fills, can be imported and then exported via the 'gridSVG' package.

hexView

cran
14th

Percentile

Functions to view files in raw binary form like in a hex editor. Additional functions to specify and read arbitrary binary formats.

hyperdraw

bioconductor
14th

Percentile

Functions for visualizing hypergraphs.

RGraphics

cran
14th

Percentile

Data and Functions from the book R Graphics, Second Edition. There is a function to produce each figure in the book, plus several functions, classes, and methods defined in Chapter 8.

BrailleR

cran
14th

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.

colorspace

cran
14th

Percentile

Carries out mapping between assorted color spaces including RGB, HSV, HLS, CIEXYZ, CIELUV, HCL (polar CIELUV), CIELAB and polar CIELAB. Qualitative, sequential, and diverging color palettes based on HCL colors are provided along with an interactive palette picker (with either a Tcl/Tk or a shiny GUI).

fontcm

cran
14th

Percentile

Computer Modern font for use with extrafont package

grid

part_of_r
14th

Percentile

A rewrite of the graphics layout capabilities, plus some support for interaction.
