Constructs a trajectory using a cell grouping and a network between groups. Will use an existing grouping if it is present in the model.

This function will generate the milestone_network and progressions.

add_cluster_graph(model, milestone_network, grouping = NULL,
  explicit_splits = FALSE, ...)

Arguments

model	The model to which a cluster graph will be added. Needs to have a cell grouping created by `add_grouping()`.
milestone_network	A network of milestones.
grouping	A grouping of the cells, can be a named vector or a dataframe with group_id (character) and cell_id (character)
explicit_splits	Whether to make splits specific by adding a starting node. For example: A->B, A->C becomes A->X, X->B, X->C
...	extra information to be stored in the wrapper.
