Package: PAC 1.1.6

PAC: Partition-Assisted Clustering and Multiple Alignments of Networks

Implements partition-assisted clustering and multiple alignments of networks. It 1) utilizes partition-assisted clustering to find robust and accurate clusters and 2) discovers coherent relationships of clusters across multiple samples. It is particularly useful for analyzing single-cell data set. Please see Li et al. (2017) <doi:10.1371/journal.pcbi.1005875> for detail method description.

Makes constellation plot, in which the centroids are clusters are embedded in the t-SNE 2D plane and the cross-sample relationships are plotted as lines connecting related sample clusters (clades).constellationPlot
F-measure Calculationfmeasure
Calculate the (global) average spread of subpopulations in clades with 2 subpopulations on the constellation plot.getAverageSpreadOf2SubpopClades
Calculates subpopulations in clades (with two or more subpopulations) that are too far away from other subpopulations (within the same clade) on the constellation plot; these far away subpopulations should be pruned away from the original clades.getExtraneousCladeSubpopulations

Wrapper to output the mutual information networks for subpopulations with size larger than a desired threshold.outputNetworks_topEdges_matrix
Outputs the representative/clade networks (plots and summary vectors) for subpopulations with size larger than a desired threshold. Saves the networks and the data matrices without the smaller subpopulations.outputRepresentativeNetworks_topEdges
Partition Assisted Clustering PAC 1) utilizes dsp or bsp-ll to recursively partition the data space and 2) applies a short round of kmeans style postprocessing to efficiently output clustered labels of data points.PAC
