v1.2.0

Released on 2023-11-06

• Changed argument data to newdata in predict methods. The argument data was deprecated.
• Bugfixes on sample_spde and when adding observations based on Euclidean positions.
• Added options vertex_unit and length_unit on graph creations. Units are given in edge lengths with the get_edge_lengths() method.
• Added a method to check if the graph is a tree.
• The graph construction was thoroughly refactored. The resulting construction is faster and cleaner.
• The graph constructions now accepts list of coordinates (where the coordinates are given as either matrices or data frames), SpatialLines, SpatialLinesDataFrames or MULTILINESTRING.
• Adding two options (sf package or sp package) for handling longlat by using the which_longlat option.
• Adding crs (if using sf) and proj4string (if using sp) for handling general coordinate reference systems.
• Moving data to the private environment.
• Several data manipulation helper tools and methods were introduced, together with a vignette with a brief tutorial on these tools.
• The method mesh_A() has been deprecated, use fem_basis() instead.
• Several quality of life improvements.
• Improved the plot() method with the option plotly=TRUE.
• Improved the plot_function() method to accept data and newdata.
• Included a process_data() method for metric graphs
• Renamed the data internal structure from "__group", "__edge_number", "__distance_on_edge", "__coord_x", "__coord_y" to ".group", ".edge_number", ".distance_on_edge", ".coord_x" and ".coord_y".
• Added an "advanced grouping" option, in which the group variable can be a combination of several columns.
• Improved graph_lme() behavior to avoid having NaN as std.errors.
• Added check for distance consistency and, more generally, check to see if the graph has euclidean edges.
• Added method get_groups() to get the unique groups, and also to retrieve the columns that were used to create the group variable.
• Added the get_data() method to get the data in a user-friendly manner.
• Added glance() and augment() methods for graph_lme() objects.
• Added get_vertices_incomp_dir() method to return vertices with incompatible directions.
• Added print(), summary(), compute_characteristics(), check_euclidean(), check_distance_consistency() methods.
• Added support for edge weights.
• Created vertices element in the metric graph object, containing information such as degrees, indegrees, outdegrees.
• Created print methods for edges, vertices, and for their entries.
• Added the improve_plot option on plot_function.
• Added support for discontinuous meshes (at the vertices).
• Added support for discontinuous functions (at the vertices) for plot_function().
