romscoords {angstroms}

Extract coordinate arrays from ROMS.

Description

Returns a RasterStack of the given variable names.

Usage

romscoords(x, spatial = c("lon_u", "lat_u"), ncdf = TRUE,
  transpose = FALSE, ...)

Arguments

x

ROMS file name

spatial

names of coordinate variables (e.g. lon_u, lat_u)

ncdf

default to NetCDF no matter what file name

transpose

the extents (ROMS is FALSE, Access is TRUE)

...

unused

Details

The two layers from the model output are used to define the real-world space. This is used to create a boundary romsboundary, to map real-world objects into grid space romscoords and to generate graticules for mapping into the grid space with graphics::contour.

Value

RasterStack with two layers of the 2D-variables

Examples

## Not run: 
  coord <- romscoord("roms.nc")

## End(Not run)
## with in-built fake data
plot(ice_fake, asp = 0.5)
contour(ice_coords[[1]], add = TRUE, levels = seq(-165, 165, by = 15))
contour(ice_coords[[2]], add = TRUE)
