open netcdf or zarr

Usage

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

# S3 method for Store
open_nz(nz, backend = NULL, warn = TRUE)

# S3 method for character
open_nz(nz, backend = NULL, warn = TRUE)

# S3 method for `NULL`
open_nz(nz, backend = NULL, warn = TRUE)

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)
}
#> Warning: Failed to open as zarr
