info function

Get information on an ERDDAP™ dataset.

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

Returns

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

Examples

## Not run:

out <- info(datasetid='erdMBchla1day')
## See brief overview of the variables and range of possible values, if given
