This is a work in progress package aiming to provide an RNetCDF-like set of functions that wrap the [`pizzarr`](https://github.com/keller-mark/pizzarr) package.

```{r demo}

z <- rnz::z_demo() # to use a directory store

# to use an http store
z <- "https://raw.githubusercontent.com/DOI-USGS/rnz/main/inst/extdata/bcsd.zarr/"

bcsd <- rnz::open_nz(z)

class(bcsd)

if(!is.null(bcsd)) {

rnz::inq_nz_source(bcsd) |> str()

rnz::inq_grp(bcsd) |> str() # only the root group supported

rnz::inq_dim(bcsd, 0) |> str()
rnz::inq_dim(bcsd, "latitude") |> str()

rnz::inq_var(bcsd, 0) |> str()
rnz::inq_var(bcsd, "latitude") |> str()

rnz::inq_att(bcsd, 0, 5) |> str()
rnz::inq_att(bcsd, "latitude", "units") |> str()

rnz::get_var(bcsd, 0) |> str()
rnz::get_var(bcsd, "latitude") |> str()
