consistency: Create, order, and plot a consistency matrix

Description Usage Arguments Details Value See Also Examples

Description

The consistency matrix is the N-by-N (for N cells) matrix where the entry in the i-th row and j-th column describes the empirical probability that cell i is ordered after cell j. These functions allow the calculation, ordering (by posterior pseudotime) and plotting of the consistency matrix. See cluster_consistency to cluster the cells using Gaussian Mixture Modelling.

Arguments

oui

A ouija_fit object

cmo

An optional ordered consistency matrix

interpolate

Passed to geom_raster

cmat

A pre-computed consistency matrix returned by consistency_matrix(oui)

Details

The consistency matrix is useful for clustering the pseudotime trajectory into discrete stages, as if there are regions where the empirical ordering probability is around 0.5 then there is large uncertainty as to the ordering, implying the cells are of roughly the same type. If the probability is closer to 0 or 1 then there is less uncertainty and the cells are probably undergoing a smooth transition.

Value

A cell-by-cell consistency matrix (ordered by posterior pseudotime if consistency_matrix_ordered), or a ggplot2 plot object displaying the ordered consistency matrix (if plot_consistency_matrix)
