open_nz(nz, backend = NULL, warn = FALSE)

# S3 method for class 'Store'
open_nz(nz, backend = NULL, warn = FALSE)

# S3 method for class 'character'
open_nz(nz, backend = NULL, warn = FALSE)

# S3 method for class '`NULL`'
open_nz(nz, backend = NULL, warn = FALSE)

Arguments

nz

a pizzarr store, a path to a zarr store, or a path to a netcdf resource

backend

character "pizzarr" or "RNetCDF" if NULL (the default) will try pizzar first and fall back to RNetCDF

warn

logical warn or no warn?

Value

ZarrGroup or NetCDF object

Examples

if(requireNamespace("pizzarr", quietly = TRUE)) {

z <- z_demo()

bcsd <- open_nz(z)

class(bcsd)

zarr <- pizzarr::DirectoryStore$new(z)

class(zarr)

bcsd <- open_nz(zarr)

class(bcsd)

}
#> [1] "ZarrGroup" "R6"       

# equivalent data in NetCDF
if(requireNamespace("RNetCDF", quietly = TRUE)) {
  nc <- z_demo(format = "netcdf")

  bcsd <- open_nz(nc)

  class(bcsd)
}
#> [1] "NetCDF"
