- graph description now recognise undirected trees
- Added pkgdown site at https://tidygraph.data-imaginist.com
- Prepare tidygraph for dplyr 1.0.0 (#118 and #119)
- Add possibility of controlling which column in
`nodes`

are used for matching if the`to`

and`from`

columns in edges are character vectors during construction (#89) `bind_graph()`

now accepts a list of graphs as its first argument (#88)- Add
`graph_modularity()`

for calculating modularity contingent on a node grouping (#97) - Edge weights are now handled more consistently to avoid igraph using a possible
`weight`

edge attribute.`weights = NULL`

will always mean that no edge weight is used (#106). - Neighborhood graph in
`map_local()`

and siblings will now contain a`.central_node`

node attribute that will identify the node from which the local graph has been calculated (#107)

- Compatibility with
`dplyr`

0.8

- Better conversion of
`network`

objects. Old conversion could mess up edge attributes. - Changes to anticipate new version of
`tibble`

and`dplyr`

`tibble`

-like dimming of non-data text in printing- Edge-length is now preserved when converting from
`phylo`

- Added
`to_subcomponent`

morpher to work with a single component containing a specified node - Morphers that reference nodes now correctly tidy eval the node argument
- Add
`node_is_adjacent`

to query which nodes are directly connected to a set of nodes - Add
`fortify`

method for`tbl_graph`

object for plotting as regular data with`ggplot2`

- Fix bug when coercing to
`tbl_graph`

from an adjacency list containing`NULL`

or`NA`

elements. - Change license to MIT
- Add
`convert`

verb to perform both`morph`

and`crystallise`

in one go, returning a single`tbl_graph`

- When collapsing edges or nodes during
`morph`

the original data will be stored in`.orig_data`

instead of`.data`

to avoid conflicts with`.data`

argument in many tidyverse verbs (**BREAKING**) `as_tbl_graph.data.frame`

now recognises set tables (each column gives eachs rows membership to that set)- Add
`with_graph`

to allow computation of algorithms outside of verbs `graph_is_*`

set of querying functions has been added that all returns logical scalars.- Add
`%N>%`

and`%E>%`

for activating nodes and edges respectively as part of the piping. `mutate`

now lets you reference created columns in graph algorithms so it behaves in line with expected`mutate`

behaviour. This has led to a slight performance decrease (millisecond scale). The old behaviour can be accessed using`mutate_as_tbl`

where the graph will only get updated in the end.- When using to_subgraph with edges, isolated nodes are no longer deleted
`bind_graphs`

now work with a single`tbl_graph`

- Added
`.register_graph_context`

to allow the use of tidygraph algorithms in external functions. - Added
`to_unfolded_tree`

,`to_directed`

, and`to_undirected`

morphers - Add the
`node_rank_*`

family of algorithms for seriation of nodes - Added
`to_hierarchical_clusters`

morpher to work with hierarchical representations of community detection algorithms. - All
`group_*`

algorithms now ensure that the groups are enumerated in descending order based on size, i.e. members of the largest group/community will always have`1`

, etc. - Fix a bug when filtering all nodes or edges where no nodes/edges would be removed (#42)
- Added interface to
`netrankr`

resulting in 19 new centrality scores and a manual mode for composing new centrality scores - Added
`edge_is_[from|to|between|incident]()`

to help find edges related to certain nodes
