Fixed a bug in the C code of Graphviz which manifests itself when the following options are given to GCC "-Wformat -Wformat-security -Werror=format-security -D_FORTIFY_SOURCE=2", this is the case for Ubuntu 12.04. Reported by Vladimir Zhurov <[email protected]>, Venkat Seshan <[email protected]> and Chong Tang <[email protected]>.
Fixed include statements in Graphviz code.
Expose mai argument in plot,Ragraph-method.
Changed the LICENSE to EPL.
Fixed some wrong text in the DESCRIPTION file.
Fixed pieGylph to adress the issue of warning messages about rep(NULL) (reported by Cristobal Fresno RodrÃguez <[email protected]>).
Updated Imports, Depends, NAMESPACE as per R CMD check requirements.
Fixing issue with the lt~obsolete.m4 file(s) in Graphviz; R CMD check was issueing a warning.
Moved vignettes from inst/doc to vignettes directory.
Backported the pieGylph fix to the release branch.
Fixing bug in Graphviz on OpenBSD regarding sincos (Thanks to Rainer Hurling).
Now using path.expand to fix tilde-expansion.
We no longer include <R_ext/RConverters.h>; which seemingly was not needed (Thanks to Brian D. Ripley).
Fix handling of fontsize attrib for nodes and edges (seems it has been broken at least since 2006).
Plotting now longer accepts border.lwd or border.col. Instead of border.col use color. Instead of border.lwd, you need to use the renderGraph/layoutGraph interface. This fixes a long standing bug where Rgraphviz writes illegal dot files. unitTest has been added.
bugfix to renderNodes (used in renderGraph) for nodes with shape = "triangle". It now works.
bugfix to renderNodes (used in renderGraph) for using node-specific lwd and shapes either "triangle", "ellipse" or "circle". It now works.
Rgraphviz now requires Graphviz >= 2.16.
Added graphvizCapabilities() that reports the capabilities of Graphviz. This requires Graphviz >= 2.28 and returns NULL if the Rgraphviz installation does not support it.
Rgraphviz now comes bundled with Graphviz 2.28, greatly simplifying installation.
Numerous bugfixes for bugs introduced in the 2.x.x versions.
