In rerddap: General Purpose Client for 'ERDDAP' Servers

Get information on an ERDDAP dataset.

Description

Get information on an ERDDAP dataset.

Usage

info(datasetid, url = eurl(), ...)

as.info(x, url)

Arguments

datasetid	Dataset id
url	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)
x	A datasetid or the output of info

Value

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
