%description
A graph community detection algorithm that aims to be performant on large
graphs and robust, returning consistent results across runs. SpeakEasy 2
(SE2), the underlying algorithm, is described in Chris Gaiteri, David R.
Connell & Faraz A. Sultan et al. (2023) <doi:10.1186/s13059-023-03062-0>.
The core algorithm is written in 'C', providing speed and keeping the
memory requirements low. This implementation can take advantage of
multiple computing cores without increasing memory usage. SE2 can detect
community structure across scales, making it a good choice for biological
data, which often has hierarchical structure. Graphs can be passed to the
algorithm as adjacency matrices using base 'R' matrices, the 'Matrix'
library, 'igraph' graphs, or any data that can be coerced into a matrix.
