A small synthetic cellspec object

Builds a small, deterministic cellspec object for examples and experiments: two images from two samples, 40 cells each, four markers (DAPI, CD3e, Pan-Cytokeratin, FOXP3) measured as mean and median in the cell and nucleus compartments, cell and nucleus areas, and one tool-specific column. The values are simulated, not measured. The random number generator state of the session is left untouched.

Usage

cs_example()

Value

A valid cellspec object with 80 cells and 19 features.
