open_ncdf

This function will read the metadata of a netCDF resource and interpret the
netCDF dimensions, variables and attributes to generate the corresponding CF
objects. The data for the CF variables is not read, please see CFVariable
for methods to read the variable data.

Network Common Data Form ('netCDF') files are widely used for
scientific data. Library-level access in R is provided through packages
'RNetCDF' and 'ncdf4'. Package 'ncdfCF' is built on top of 'RNetCDF' and
makes the data and its attributes available as a set of R6 classes that are
informed by the Climate and Forecasting Metadata Conventions. Access to the
data uses standard R subsetting operators and common function forms.

open_ncdf function

<dl><dt>resource</dt>
<dd>The name of the netCDF resource to open, either a local file
name or a remote URI.</dd>
<dt>keep_open</dt>
<dd>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
<code><a href="/link/close()?package=ncdfCF&version=0.4.0" data-mini-rdoc="ncdfCF::close()">close()</a></code> after use. Note that when a data set is opened with
<code>keep_open = TRUE</code> the resource may still be closed by the operating system
or the remote server.</dd></dl>
