Create simple feature geometry list column, set class, and add coordinate reference system and precision
st_sfc(
...,
crs = NA_crs_,
precision = 0,
check_ring_dir = FALSE,
dim,
recompute_bbox = FALSE
)
zero or more simple feature geometries (objects of class sfg
), or a single list of such objects; NULL
values will get replaced by empty geometries.
coordinate reference system: integer with the EPSG code, or character with proj4string
numeric; see st_as_binary
see st_read
character; if this function is called without valid geometries, this argument may carry the right dimension to set empty geometries
logical; use TRUE
to force recomputation of the bounding box
an object of class sfc
, which is a classed list-column with simple feature geometries.
A simple feature geometry list-column is a list of class
c("stc_TYPE", "sfc")
which most often contains objects of identical type;
in case of a mix of types or an empty set, TYPE
is set to the
superclass GEOMETRY
.
