This function launches an interactive Shiny application for visual exploration and selection of features within a given dataset. It allows users to interactively select features based on various criteria and visualization tools such as tangents, areas, nearest points, and polygons.
fov_selection(object = NULL)An STGrid object. Alternatively, a dataframe or a matrix that contains the coordinates (x, y) and the feature label. It thus should have at least three columns x (x-coordinates), y (y-coordinates), and feature (feature labels). Additional columns are supported.
Launches a Shiny application which does not return a value to the R environment. Selected features and configurations can be exported directly from the application interface.
