register_caugi_edge(glyph, tail_mark, head_mark, class, symmetric = FALSE)

Arguments

Examples

# first, for reproducability, we reset the registry to default
reset_caugi_registry()

# create a new registry
reg <- caugi_registry()

# register an edge
register_caugi_edge(
  glyph = "<--",
  tail_mark = "arrow",
  head_mark = "tail",
  class = "directed",
  symmetric = FALSE
)

# now, this edge is available for caugi graphs:
cg <- caugi(A %-->% B, B %<--% C, class = "DAG")

# reset the registry to default
reset_caugi_registry()
