Get information on an ERDDAP dataset.
info(datasetid, url = eurl(), ...)
as.info(x, url)
Dataset id
A URL for an ERDDAP server. Default:
https://upwell.pfeg.noaa.gov/erddap/ - See eurl()
for
more information
Further args passed on to crul::verb-GET (must be a named parameter)
A datasetid or the output of info
Prints a summary of the data on return, but you can index to various information.
The data is a list of length two with:
variables - Data.frame of variables and their types
alldata - List of data variables and their full attributes
Where alldata
element has many data.frame's, one for each variable,
with metadata for that variable. E.g., for griddap dataset
noaa_pfeg_696e_ec99_6fa6
, alldata
has:
NC_GLOBAL
time
latitude
longitude
sss
