Description Usage Arguments Value Examples
These functions return the noncoordinate information of a geometry and/or vector. They do not parse an entire geometry/vector and are intended to be very fast even for large vectors.

handleable 
A geometry vector (e.g., 
... 
Passed to the 
geometry_type 
An integer code for the geometry type. These integers follow the WKB specification (e.g., 1 for point, 7 for geometrycollection). 
geometry_type_label 
A character vector of (lowercase) geometry type labels as would be found in WKT (e.g., point, geometrycollection). 
A data.frame with columns:
geometry_type
: An integer identifying the geometry type.
A value of 0 indicates that the types of geometry in the vector
are not known without parsing the entire vector.
size
: For points and linestrings, the number of coordinates; for
polygons, the number of rings; for collections, the number of
child geometries. A value of zero indicates an EMPTY geometry.
A value of NA
means this value is unknown without parsing the
entire geometry.
has_z
: TRUE
if coordinates contain a Z value. A value of NA
means this value is unknown without parsing the entire vector.
has_m
: TRUE
if coordinates contain an M value. A value of NA
means this value is unknown without parsing the entire vector.
srid
: An integer identifying a CRS or NA if this value was not
provided.
precision
: A grid size or 0.0 if a grid size was not provided.
Note that coordinate values may not have been rounded; the grid
size only refers to the level of detail with which they should
be interpreted.
