subsampling_feature_extraction.RdExtract measurements from sampled_data.frame and polygons
subsampling_feature_extraction(sampled_polygons, sampled_data)SpatialPolygonsDataFrame, containing the cell polygons.
Data.frame, containing the measurements for all cells (some empty columns because all cell types included in one file)
A vector with whole-image values.
This function is designed to be used when the image has already
been processed and all cells have already been measured (e.g.
when evaluating sampling effort). For unmeasured images, see
extract_image_features().
