lazysf: Delayed Read for 'GDAL' Vector Data Sources

Lazy read for drawings. A 'dplyr' back end for data sources supported by 'GDAL' vector drivers, that allows working with local or remote sources as if they are in-memory data frames. Basic features works with any drawing format ('GDAL vector data source') supported by the 'sf' package.

Package Options

There is a debug option options(lazysf.query.debug = TRUE) which if set will cause the generated SQL statement to be printed before every call to sf::st_read(). In addition it will print the number of rows actual read.
