Deprecated functions in sf — sf-defunct • sf

These functions are provided for compatibility with older version of sf. They will eventually be completely removed.

Use st_read() instead of st_read_db().
Use st_write() instead_of st_write_db()

Usage

st_read_db(
  conn = NULL,
  table = NULL,
  query = NULL,
  geom_column = NULL,
  EWKB = TRUE,
  ...
)

st_write_db(
  conn = NULL,
  obj,
  table = deparse(substitute(obj)),
  ...,
  drop = FALSE,
  append = FALSE
)

Arguments

conn: open database connection
table: table name
query: SQL query to select records; see details
geom_column: deprecated. Geometry column name
EWKB: logical; is the WKB of type EWKB? if missing, defaults to TRUE
...: parameter(s) passed on to st_as_sf

Details

The geom_column argument is deprecated. The function will automatically find the geometry type columns. For the RPostgreSQL drivers it will try to cast all the character columns, which can be long for very wide tables.
