Changes in rgexf version 0.17.0 (2026-07-22)

rgexf is back on CRAN! The package was archived on CRAN on 2026-05-18 because outstanding check issues were not corrected in time. This release fixes those issues and returns the package to CRAN.

New features and changes

  • plot.gexf() now renders graphs as an interactive htmlwidget powered by sigma.js v3 and graphology. Node positions, colours, and sizes are read from the viz:* attributes in the GEXF document.

  • New sigmajs() function creates a sigma.js htmlwidget from a gexf object or a path to a .gexf file. Shiny helpers sigmajsOutput() and renderSigmajs() are also available.

  • The legacy gexf-js file-server renderer is preserved as plot_gexfjs(). The gexfjs() htmlwidget (inline iframe approach) is likewise kept for backward compatibility.

  • gexfjs() now accepts a gexf object in addition to a file path, matching sigmajs().

  • gexfjs() has an explicit sizing policy: the widget now defaults to the full available width ("100%") and a height of "400px" in knitr documents, the browser, and Shiny alike. Both gexfjs() and sigmajs() honor user-supplied width/height, and their documented defaults were clarified.

Bug fixes

  • The gexfjs() widget rendered an empty main canvas: the bundled config.js (which sets zoomLevel, showEdges, and other gexf-js defaults) was never loaded into the iframe, making every screen coordinate NaN.

  • Icons and images in the gexfjs() widget (zoom, lens, edge buttons, search icon, Gephi logo) did not display: relative url(...) references in the CSS cannot resolve inside a srcdoc iframe, so images are now inlined as base64 data URIs.

  • The gexfjs() widget’s node-attribute panel was blank and search did not work: the generated DOM was missing the #leftcontent element, the search form id had a typo (reacherche), and the autocomplete list was clipped by the title bar.

Changes in rgexf version 0.16.3 (2024-06-27)

CRAN release: 2024-07-01

  • Dynamically loaded components in the Rd files were removed to comply with new CRAN policies.

Changes in rgexf version 0.16.2 (2021-08-10)

CRAN release: 2021-08-12

New features and changes

  • We now have a hex sticker!

  • Users can now cite properly rgexf with JOSS (see citation(package="rgexf")).

  • Added a few extra breaks across the examples (suggested by @corneliusfritz).

  • Improved documentation regarding spells and dynamic graphs (suggested by @jonjoncardoso).

  • New head() function allows a glimpse of the n first nodes/edges.

Bug fixes

  • Passing colors with four values (alpha) no longer fails during checks. (reported by @IsabelFE).

  • The summary function prints nodes’ attributes as expected.

  • Hex colors now work (#41 reported by @milnus).

  • gexf.to.igraph correctly processes edge attributes (#38 reported by @balachia).

  • Time range is now correctly computed (#19).

  • Non-integer ids were incorrectly processed when reading GEXF files.

Changes in rgexf version 0.16.0 (2018-02-05)

CRAN release: 2020-02-17

New features and changes

  • Function write.gexf has a new argument for specifying the GEXF version for now it only changes the header.

  • plot.gexf method now uses gexf-js instead of sigma.js.

  • Now igraph.to.gexf passes arguments to gexf. Before, it was only passing position. This way users have more flexibility specifying attributes.

  • gexf’s nodesVizAtt now has defaults for color, size, and position; this is a requirement of gexf-js.

  • gexf ’s nodesVizAtt color and size now support passing a default for all the nodes. Also, color can be specified as a character scalar (name of the) color, or as an integer (number in colors()).

  • gexf has a new argument, rescale.node.size. When set to TRUE, the size vector in nodesVizAtt is rescaled such that when calling the plot method the largest node spans roughly 5% of the plot.

  • read.gexf now parses viz attributes (color, position, and size).

  • igraph.to.gexf and vice versa now pass viz attributes and layout.

New functions

  • The function gexf has been introduced as an eventual replacement of write.gexf since it makes more sense. write.gexf should only be for writing the gexf file on the disk (effective starting vers 0.17.0).

Misc changes

  • Modernization of the project (roxygen, new CRAN standards, etc.)

  • Updated emails.

  • Remove broken links.

  • Some data management functions were fully ported to R.

Changes in rgexf version 0.15.3 (2015-03-24)

CRAN release: 2015-03-24

  • Updating emails.

Changes in rgexf version 0.14.3 (2014-03-09)

New features and changes

  • New option -digits- in several functions allows controlling for printing precision (reported in issue 16, thanks Nico!).

  • Function -igraph.to.gexf- now imports attributes.

Bug fixes

  • Option -defaultedgetype- in the -write.gexf- function now works for static graphs (reported in issue 17, thanks Avitus!).

  • Correcting errors in -plot.gexf- method, now visual attributes are imported correctly.

Development

  • Option -keepFactors- default is now in -FALSE- (used to be in -TRUE-). When set to -TRUE- and there are factors, a warning message will appear (reported in issue 18, thanks to Tim Smith!).

Bug fixes

  • Included class checks in -gexf- class functions (thanks to Samuel Finegold).

CRAN release: 2013-03-14

New features and changes

  • New functions add.node.spell and add.edge.spell now allow to work with nodes and edges time spells.

  • New function check.dpl.edges, written in C, analyzes links and reports duplicates (marking them) and number of times the same link is repeated considering if the graph is directed or not.

  • New function switch.edges, also written in C, allows to order links representations (source and target) in order to set the smallest id as source and the highest as target.

  • Function write.gexf now has an improved error handler. Now parses objects before even opening the XML graph.

  • Edges support id assignment and labeling.

Bug fixes

  • Small bug detected in viz attributes fixed.
