mfd_read_db: Read simple features from the Manifold driver

In mdsumner/manifoldr: Facilities for Manifold System

Description

Read a drawing from a Manifold connection.

Usage

mfd_read_db(con = NULL, table, query = "", geom_column = NULL,
  WHERE = "", ..., quiet = TRUE)

Arguments

con	connection object
table	table to read, can be a Drawing name or its child table
query	query to run, optional
geom_column	this is the name of the column as returned (not the name of the column natively)
WHERE	optional WHERE clause, as in "WHERE ID = 1 AND size < 10"
...	other arguments passed along (none currently)
quiet	keep quiet by default

Details

By default the entire drawing is read with all non-intrinsic columns. The intrinsic column "Geom (I)" is cast to WKB within Manifold and then interpreted using st_as_sfc.
