The NumericAnnotation - Class

An S4 class designed to represent the spatial extent of data points, such as cells or barcoded spots, by filtering and outlining them according to their values for a specific numeric variable. This class is particularly suitable for creating annotations that highlight areas of interest based on continuous characteristics like gene expression or other numeric attributes derived from spatial multi-omic datasets.
