Constructs a trajectory using a graph between cells, by mapping cells onto a set of backbone cells.

This function will generate the milestone_network and progressions.

add_cell_graph(model, cell_graph, to_keep,
  milestone_prefix = "milestone_", ...)

Arguments

model	The model to extend
cell_graph	The edges between cells. Format: Data frame(from = character, to = character, length(optional) = numeric, directed(optional) = logical)
to_keep	A named vector containing booleans containing whether or not a cell is part of the backbone. Or, alternatively a character vector containing the backbone cells
milestone_prefix	A prefix to add to the id of the cell ids when they are used as milestones, in order to avoid any naming conflicts,
...	extra information to be stored in the wrapper.
