Crop a ROMS layer — croproms • angstroms

Crop a ROMS data layer from romsdata with a raster extent.

croproms(x, ext, ...)

Arguments

x	ROMS xy- coordinates, see `romscoords`
ext	`raster::extent` in the coordinate system of `x`
...	ignored

Details

The spatial crop is performed in the coordinate space of roms data.

Examples

## notice that extent is in long-lat, but ice_local is in the grid
## space of ice_coords
ice_local <- croproms(ice_coords, extent(100, 120, -75, -60))
plot(ice_coords[[2]], col = grey(seq(0, 1, length  = 20)))
plot(crop(ice_fake, ice_local), add = TRUE)
