dataseries 1.0.0

This is a ground-up rewrite. dataseries.org now serves its data through a public API (api.dataseries.org), and the package has been rebuilt around it. The old flat series identifiers (e.g. "CCI.AIK") no longer exist, so this release is not backward compatible.

New data model

• Data is now organized into datasets, most of which are multi-dimensional cubes. A single series is one cell, addressed by a dataset plus one code per dimension.

New and changed functions

• ds(dataset, ..., from, to, class) is the new download function. The first argument is a dataset id; dimension filters are passed as named arguments (e.g. ds("ch_seco_gdp", type = "real", structure = "gdp")). The default data.frame is returned in long (tidy) format; class = "ts" lays the selected series out as columns. The xts option (and the xts dependency) has been dropped, as all series are regular-frequency and covered by ts.
• ds_catalog() lists all datasets (replaces inventory()).
• ds_search(pattern) is a flat, searchable list of the individual series across all datasets — the finest-grained way to discover what exists.
• ds_meta(dataset) returns a dataset’s dimensions and codes, for discovery.
• inventory() is deprecated; it now warns and calls ds_catalog().
• cache_ls() / cache_rm() continue to manage the in-memory cache.

dataseries 0.2.0
