Package: EmbedSOM 2.2.1

EmbedSOM: Fast Embedding Guided by Self-Organizing Map

Provides a smooth mapping of multidimensional points into low-dimensional space defined by a self-organizing map. Designed to work with 'FlowSOM' and flow-cytometry use-cases. See Kratochvil et al. (2019) <doi:10.12688/f1000research.21642.1>.
