GeomEdgeTile now uses edge_width instead of edge_size for the bordergeom_edge_parallel() when used with edge labels. Edges are now correctly offset, though label may still overlap (#227)get_con() that would lead to wrong matching of additional data (#249)na.rm in geoms (#301)check_overlap = TRUE in geom_node_text() the rendering order is reversed so that the top nodes are rendered, not the bottom onesguide_edge_direction(), this update adds the option to use labels instead of an arrow using the labels argument.create_layout() now returns a modified tibble rather than a data.frame... in get_nodes(), get_edges(), and get_con() now accepts tidy evaluation. get_nodes() and get_con() will get evaluated on the node data in the original order (layouts may reorder nodes), and get_edges() will get evaluated on the edge data (#272)weight argument allowing you to set how much space each node occupy. Further, the layout now calculates statistics so that it can be used in conjunction with geom_node_tile() and geom_node_arc_bar()geom_edge_bundle_force(), geom_edge_bundle_path(), and geom_edge_bundle_minimal() (+ variants) to provide support for edge bundling (#267)layout_sf(), geom_node_sf() and geom_edge_sf() to support plotting of sfnetwork objects (#275)facet_graph() when using . on either dimension (#313)layout in create_layout() (#208)dim to a value higher than 2 in igraph layouts (#160)label_colour to NA would turn it off instead of inheriting the colour of the edge (#238)native now works as expected again (#254)get_con() that would require input to be sorted in the from vector (#258)geom_edge_elbow() that resulted in duplicated group columns in the data.qgraph() in favour of autograph() to avoid name collision with qgraph::qgraph(). autograph() is now also a generic with a default method, so you can provide your own specific ggraph plot method for your network classesThis release is a major release including many new features, bug fixes and some breaking changes.
Use tidygraph as the central data format. The results of this are several:
"even" layout for dendrograms are no more, but can be obtained by using the "dendrogram" layout with height = NULLtree_apply has been removed in favour of using tidygraph::map_bfs_*geom_edge_elbow is no longer only available to dendrogram objectssort.by = node_rank_hclust() in your specification of a linear layout, or aes(colour = group_infomap()) in node geomscurvature argument from geom_edge_arc() and geom_edge_hive() as well as the spread argument from geom_edge_fan() has been deprecated in favor of the new strength argument.ggraph plots now gets constructed with grid and axes removed from the default theme.
geom_edge_parallel() for drawing multiedges as parallel lines (#191)geom_node_range() and geom_edge_span() for visualising such layouts (#47)geom_edge_bend() for drawing soft elbows (#45)geom_node_voronoi() for displaying nodes as voronoi tiles (#100)qgraph() for quickly creating a standard network plot for explorative purpose (#94)strength parameter that controls their deviation from a straight line. 0 will always give a straight line while 1 will be their natural look. Numbers outside this range may look weird (#97)weight and mode arguments to get_con() that are passed on to the shortest path calculations (#89).geom_edge_point() (#23)geom_edge_tile() for use with matrix layouts (#141)x and y argument is present, the auto layout will choose the manual layout. (#91)data.frame or an object coercible to a tbl_graph. In the latter case the node table will be used as layout and the graph will be attached. This allows direct use of the particles package as a layout engine as a side effect. (#88)label_parse = TRUE (#159)facet_graph() with data from both tbl_df and data.frameoverride.aes to guide_edge_direction()
