dmdims: Fetch dimensions of a DataMarket dataset.

In rdatamarket: Data access API for DataMarket.com

Description

Get a list of dataset dimension objects for the given dataset.

Usage

dmdims(ds, .params = list())

Arguments

ds

a dataset ID, DS string, URL query-string, or whole URL. The DS string to send is extracted from the URL as needed, and short URLs at data.is, bit.ly, is.gd, t.co and url.is are expanded. If the DS string contains dimension filter specifications (the stuff after the ! character, so it's not just a dataset ID), these are preserved in the request to the API, but for normal DataMarket datasets they do not affect the response.

.params

extra GET parameters to pass along in the API request.

Value

named list of dataset dimension information. Each name is a dataset ID and each element is a named list of dimensions of that dataset. Each dimension is named for its dimension ID in that list, and is itself a named list of the four properties id, title, type, values. The first three of these properties are character strings, while values is a named list of dimension values. Each of these is a list of two properties id, title, and the id is also the name of the dimension value

Examples

dmdims("17tm")
dmdims("17tm!kqc=a")
dmdims("ds=17tm")
dmdims("ds=17tm!kqc=a")
dmdims("foo=bar&ds=17tm&baz=xyzzy")
dmdims("http://datamarket.com/api/v1/series.json?foo=bar&ds=17tm&baz=xyzzy")
dmdims("http://datamarket.com/data/set/17tm/#ds=17tm")
