Passing command line arguments to st_read

[davidorme]

Is there a way to pass OGR command line options in st_read? The specific use case is that I wanted to load a small spatial subset of a large file, which I'd do on the command line using -spat xmin ymin xmax ymax. The query argument works beautifully for getting a subset by feature attribute, but not spatial queries.

More of a feature request than an issue...

Good idea! See https://github.com/r-spatial/sf/blob/master/tests/read.R#L139-L144 for an example.

I chose to pass a geometry as WKT, rather than four numbers; I believe the implementation by OGR in the end is identical, in the sense that overlap with bounding box is given; see here.

Perfect. Thanks, Edzer.
