# tidygraph 1.1.2 2019-02-18

• Compatibility with dplyr 0.8

# tidygraph 1.1.1 2018-11-20

• 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

# tidygraph 1.1.0 2018-02-10

• Fix bug when coercing to tbl_graph from an adjacency list containing NULL or NA elements.
• 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
