assignCellClusterNearestNode: Assign cells to a reference cell subtype
In phemd: Phenotypic EMD for comparison of single-cell samples

Description Usage Arguments Details Value Examples

Assigns each cell in cur_cells to a cluster based on nearest cell in Monocle 2 tree

assignCellClusterNearestNode(
  cur_cells,
  ref_cells,
  ref_cell_labels,
  cell_model = c("monocle2", "seurat", "phate")
)

`cur_cells`	Matrix of cells to be assigned to clusters (Dim: `num_cells` x `num_markers`)
`ref_cells`	Matrix of cells used to build reference Monocle 2 tree (Dim: `num_monocle_cells` x `num_markers`)
`ref_cell_labels`	Vector of length `num_monocle_cells` containing Monocle 2 cell branch assignments
`cell_model`	Either "monocle2", "seurat", or "phate" depending on method used to model cell state space

Private method (not exported in namespace). Uses RANN package for fast knn search

Vector of length num_cells representing cluster assignments for each cell in cur_cells
