Visualization of four-component unmixing results from the lung cancer data of Jones et al. . (a) All components and tumor samples. Tumor samples appear as red points and components as blue X's labeled by numbers. (b-d) Three views of the same data with distinct clinical subtypes highlighted. Components appear as blue X's labeled by numbers. Tumors are marked as follows: normal lung tissue (black point), large cell carcinoma (blue star), carcinoid (cyan asterisk), adenocarcinoma (yellow circle), large cell neuroendocrine (green diamond), small cell primary tumors (red upward-pointing triangles), small cell cell lines (magenta downward-pointing triangles). The two primary combined small cell/adenocarcinoma samples were omitted from (b-d).
