I need a method viable to pre-determine the Resolution Parameter in Leiden algorithm for Community detection, using the "Modularity" objective function (instead of CPM). I read several documents but couldn't find a consistent way to implement it in R code. Anyone has encountered a similar challenge?
I tried to manually adjust the Resolution Parameter and finally I decided to make the algorithm find the parameter automatically, disabling the resolution parameter and the vertex weight, as specified in the documentation, but wanted to find a more accurate way. Here's the code I used.
communities_auto <- cluster_leiden(graph2,
objective_function = "modularity",
weights = E(graph2)$weight,
(#)resolution_parameter = 1.05
n_iterations = 1000)
