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

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)

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)

  • 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!).

  • -datetime- time format in -write.gexf- now works for other formats different from numeric datetime types (reported as issue 15, thanks Thomas Ullmann!).

  • 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!).

Changes in rgexf version 0.13.11 (2013-11-27)

Bug fixes

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

  • write.gexf does not fails when dynamics different from double are passed (thank you, Samuel Finegold!).

  • Passing weights from igraph to gexf has now been fix (thank you Roberto Brunelli!).

  • Fixing encoding issues thanks to Yong Cha's suggestion (thank you!).

Changes in rgexf version 0.13.8 (2013-08-06)

New features and changes

  • New S3 method plot.gexf, implemented by Joshua B Kunst, shows the graph in the web browser by means of Sigma.js (!).

  • New functions igraph.to.gexf and gexf.to.igraph converts objects between igraph and gexf classes. Colors and attributes are preserved.

Development

  • Improving general documentation.

  • Just starting to add new options to add.gexf.node/edge, more precisely, passing attributes.

Changes in rgexf version 0.13.05 (2013-05-09)

Bug fixes

  • sprintf error when using other formats rather than double (issue 10).

  • in .addNodesEdges, add support to case “!attributes && vizattributes” (issue 9).

Changes in rgexf version 0.13.03 (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.

  • Edges thickness viz att XML representation (viz:thickness) was replaced by viz:size (as it should be).

  • "Library" replaced by "Package" everywhere (ups!)

Development

  • .addNodesEdges rewritten now works faster in most of CPUs (some of them with very high speedups) (Thanks to Duncan Temple Lang, RXML author)

  • Several code routines have been extracted from "bigger functions" and written as functions themselves.

Changes in rgexf version 0.13.01 (2013-01-04)

New features and changes

  • New functions new.gexf.graph, add.gexf.node, add.gexf.edge, rm.gexf.node and rm.gexf.edge allow to build and manipulate gexf objects from scratch.

  • New function read.gexf allows to import gexf files as gexf class objects.

  • gexf function now it is called write.gexf.

  • Edges now allow weighting.

  • Viz Attributes (color, shape, size, etc.) can be included in both, nodes and edges.

  • Real-life datasets have been included.

  • New function edge.list builds a dataframe of nodes from an edge list.

  • New methods for gexf objects: print.gexf and summary.gexf.

Development

  • gexf class objects are now a standard.

  • Function gexf is now named write.gexf.

  • Faster net build.

  • More demos + improve ones.

  • Cleaner code.

Changes in rgexf version 0.12.03.29 (2012-03-29)

Bug fixes

  • Fixing big issue at attvalues XML tag: it was replaced from "att" to "attvalue".

  • Fixing problem with XML value printing: Leading spaces where removed from XML values at ids, source, target, etc.

Changes in rgexf version 0.12.03 (2012-03-05)

New features and changes

  • Including a manual of the functions

Development

  • Development repository more ordered according to R package building.
