undirected graph from adjacency matrix without symmetric matrix

4

The docs say the following when mode is "undirected" (and weighted =TRUE): > First we check that the matrix is symmetric. It is an error if not. Then only the...

delete_edges bug and counterintuitive add_edges behaviour (and workaround)

20

**Describe the bug** The documented behaviour of `delete_edges` is not correct, and `add_edges` does some counterintuitive things. **To reproduce** ```R library('igraph') set.seed(1) G = make_ring(10) E(G)$color='blue' e = get.edgelist(G) #...

Slower speed vs basic edgelist in some tasks

15

Thanks for all your work building & maintaining this package. I was exploring custom network generating functions directly in R, and started benchmarking speeds. To my surprise, working directly with...

Nice to have: Plot self-loops so that they face away from other edges

**What is the feature or improvement you would like to see?** In layout_in_circle: always plot self edges outside the circle. **Use cases for the feature** Example. ``` # Berger/circle schedule...

cluster_leiden() docs should be explicit about the objective function

15

The `cluster_leiden()` documentation does not have the formula for the objective function. What is being maximized using `CPM` and `modularity`, respectively? Additionally, since `CPM` is the default, the docs should...

Indexing edge/vertex sequences is prone to name conflict

21

**Describe the bug** When indexing into edge or vertex sequences, attribute names are interpreted specially, as documented: https://igraph.org/r/html/latest/igraph-es-indexing.html and https://igraph.org/r/html/latest/igraph-vs-indexing.html > E.g. if a graph has a `name` vertex attribute,...

bfs()/dfs() adds NA into 'father' vector, which then causes trouble later

9

**Describe the bug** The `bfs()` and `dfs()` functions produce a 'father' vector that contains `NA` for the root. This is in fact not a vector, but an `igraph.vs`, where it...

Label propagation "initial" parameter should be treated as index vector

2

The `initial` parameter of `cluster_label_propagation` now takes a vector with values in the range `[0, n-1]` where `n` is the vertex count. Values outside this range are rejected by the...
