romscoords | R Documentation |
Returns a RasterStack of the given variable names.
romscoords(
x,
spatial = c("lon_u", "lat_u"),
ncdf = TRUE,
transpose = TRUE,
...,
varname = "",
flip_y = TRUE
)
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 |
varname |
in desperate cases, specify the variable that these coordinate variables belong to |
flip_y |
Y coordinates are assumed to be in top-down order, set to FALSE to assume down-up |
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
.
