(#852).identical_graphs()
now correctly detects identical graphs without node or edge attributes (#757).Change ownership rules of attribute objects (#870).
R_SEXP_to_igraph()
and R_SEXP_to_igraph_copy()
get igraph_t
object from external pointer (#865).
Remove ETIME()
call from Fortran code, already in CRAN version 1.5.0.1 (#858).
Ensure that _GNU_SOURCE
is always defined (#877).
Fix make clean
(#860).
Fix generation of code for functions with VERTEX_COLOR
out-arguments (#850).
Use -lquadmath
in Makevars.win
, for compatibility with alternative R distributions such as Microsoft R Open (#855).
getRversion()
uses strings.
Add cffr file and a GHA workflow that updates it automatically (#873).
Undeprecate neighborhood()
(#851).
Remove redundant reference to AUTHORS from DESCRIPTION.
estimate_betweenness()
, estimate_edge_betweenness()
, estimate_closeness()
(#852).ETIME()
call from Fortran code.The internal format of graph objects has changed in a mostly backward-compatible way, to prepare for upgrading the C core to 0.10. Details are described at https://github.com/igraph/rigraph/wiki/The-igraph-object-format. Accessing graph objects that have been created with an older igraph version give a clean error message with instructions (#832). The new format cannot be read by igraph 1.4.3 or older, the following error is raised when trying to do so:
This graph was created by an old(er) igraph version.
Call upgrade_graph() on it to use with the current igraph version
For now we convert it on the fly...
Error in is_directed(object) :
REAL() can only be applied to a 'numeric', not a 'NULL'
The only supported remedy is to upgrade the igraph package to version 1.5.0 or later.
graph_version()
now returns an integer scalar (#832, #847), 4
as of igraph 1.5.0 (#835).
Vertex and edge sequences are converted to numeric vectors when used in attributes (#808).
New largest_component()
returns the largest connected component (#786, @ngmaclaren).
make_graph()
when simplify = ...
is used with a non-formula (#834).Add more tests for graph_from_literal()
(#826).
Reenable serialization test and tests for dyad_census()
, stabilize tests (#809, #822, #823).
The documentation for the R package is now hosted at https://r.igraph.org/ (#780).
Update vignette("installation-troubleshooting")
.
Fix use of deprecated functions in examples, e.g., replace gsize()
by ecount()
(#827).
Fix typos in ?eigen_centrality
docs (@JJ).
Update CONTRIBUTING.md and ORCID information (#791, #774).
Add DOI to CITATION (#773).
Add data for old igraph versions as constructed objects, and tests (#838).
Ensure we're always using named indexes to access the internal data structure (#784).
Prepare migration to igraph/C 0.10 (#781).
Update generated interface (#765).
Remove igraph.eigen.default()
and eigen_defaults
, introduce internal eigen_defaults()
as a function (#741).
Remove broken nexus*()
functions (#705), and srand()
(#701).
Update C core.
ARPACK-based calculations are now interruptible.
shortest_paths()
and all_shortest_paths()
no longer crash when an invalid from
vertex is passed and weights are being used.
See diff for details.
Use true vertex names for printing vertex sets. If a vertex set captures a relationship between vertices (e.g., the father
component of bfs()
), the vertex set is printed as a named vector (#754).
Suggest restarting R session after fatal error (#745).
as_long_data_frame()
now correctly processes vertex attributes and works with graphs without vertex attributes (#748).
as.hclust(hrg.fit(g))
works again (#721).
The documentation is now available at https://igraph.org/ (#743).
Reorganize function reference (#662).
Replace graph()
with make_graph()
in examples (#738).
Add docs for as.hclust.igraphHRG()
(#733).
Merged man page of hub_score()
and authority_score()
(#698).
Refactor contributors listing (#647).
Improve "family" titles (#679).
Improve docs of ego/neighborhood functions.
Improve transitivity()
docs.
Introduce cpp11 package to improve error handling in the long run (#720).
Avoid longjmp for error handling and interrupts (#751).
as.hclust.igraphHRG
uses .Call()
interface (#727).
console()
now works again and provides a Tcl/Tk based UI where igraph can post status messages and progress info (#664).
Fix errors when printing long vertex names (#677, @ahmohamed).
Fix regression that broke builds on some systems (e.g., GCC version 5 or earlier), introduced in igraph 1.4.0 (#670, #671).
fit_hrg()
does not crash any more when called with a graph that has less than three vertices.
Fix warning about yyget_leng()
returning wrong type when using LTO (#676).
Don't mention C++11 or C++17 for best compatibility with both newest R and older compilers, while still requesting a C++ compiler for linking.
Don't ignore build/
when building the package because the vignette index is built there.
Skip plot test entirely on R-devel.
Avoid submodules for building igraph (#674).
Makevars cleanup (#671).
Add Zenodo configuration file.
