Label propagation

Description

Label propagation

Usage

propagate_labels(
  edge_verts,
  edge_weights,
  vert_labels,
  max_n_iters = 10L,
  verbose = TRUE,
  diffusion_fading = 10,
  diffusion_fading_const = 0.5,
  tol = 0.005,
  fixed_initial_labels = FALSE
)

Arguments

edge_verts	edge vertices of igraph graph object
edge_weights	edge weights of igraph graph object
vert_labels	vector of factor or character labels, named by cell names
max_n_iters	integer Maximal number of iterations (default=10)
verbose	boolean Verbose mode (default=TRUE)
diffusion_fading	numeric Constant used for diffusion on the graph, exp(-diffusion.fading * (edge_length + diffusion.fading.const)) (default=10.0)
diffusion_fading_const	numeric Another constant used for diffusion on the graph, exp(-diffusion.fading * (edge_length + diffusion.fading.const)) (default=0.5)
tol	numeric Absolute tolerance as a stopping criteria (default=5e-3)
fixed_initial_labels	boolean Prohibit changes of initial labels during diffusion (default=FALSE)

Value

matrix from input graph, with labels propagated
