crown_inspector: Inspect Delineated Crowns In Multiple Images
In pieterbeck/CanHeMonR: Tools for canopy health monitoring through image analysis

For a given set of SpatialPoints, and a set of images and associated .shp file of delineated crowns, plot the crown delineated around each of the spatial points in each of the images.

1 2	crown_inspector(spatial_points, image_fnames, RGBseqs, crown_fnames, outp_dir, overwrite = T)

`spatial_points`	A SpatialPoints object
`image_fnames`	Filenames of images
`RGBseqs`	A 3 row matrix that indicates for each image which band nummers to display as red, green, and blue, respectively. It should have as many columns as image_fnames is long.
`crown_fnames`	Filenames of the vector (e.g. crown polygon) shapefiles associated with each of the images in image_fnames. The shapefiles must have the attributes primalX and primalY, which refer to the coordinates of the centers of the crowns in a reference image
`outp_dir`	Character. Directory where plots for each crown are stored
`overwrite`	Logical. Should the outp_dir be emptied prior to plotting? Default is T. Setting it to F can be handy when the code needs to be rerun after an unexpected interruption.
