Build the graph now

Source: R/verbs.R
build.Rd

If a caugi has been modified (nodes or edges added or removed), it is marked as not built, i.e cg@built = FALSE. This function builds the graph using the Rust backend and updates the internal pointer to the graph. If the graph is already built, it is returned.

Usage

build(cg, ...)

Arguments

cg

A caugi object.

...

Not used.

Value

The built caugi object.

Examples

# initialize empty graph and build slowly
cg <- caugi(class = "PDAG")

cg <- cg |>
  add_nodes(c("A", "B", "C", "D", "E")) |> # A, B, C, D, E
  add_edges(A %-->% B %-->% C) |> # A --> B --> C, D, E
  set_edges(B %---% C) # A --> B --- C, D, E

cg <- remove_edges(cg, B %---% C) |> # A --> B, C, D, E
  remove_nodes(c("C", "D", "E")) # A --> B
