open_ncdf {ncdfCF}

Read a NetCDF resource

Description

Read a NetCDF resource

Usage

open_ncdf(resource, keep_open = FALSE)

Arguments

resource

The name of the NetCDF resource to open, either a local file name or a remote URI.

keep_open

Logical flag to indicate if the NetCDF resource has to remain open after reading the metadata. This should be enabled typically only for programmatic access or when a remote resource has an expensive access protocol (i.e. 2FA). The resource has to be explicitly closed with close() after use. Note that when a dataset is opened with keep_open = TRUE the resource may still be closed by the operating system or the remote server.

Value

An ncdfDataset instance, or an error if the resource was not found or errored upon reading.
