dvn-package | R Documentation |
Access legacy Dataverse (version 3 and below) installations.
Provides access to The Dataverse Network Data Sharing and Data Deposit APIs for legacy Dataverse installations (versions 3 and below). For current Dataverse installations (versions 4 and above), use “dataverse,” the official R client for Dataverse.
The Data Sharing API provides access to archived data (and metadata). The dvn package provides a number of functions to translate API responses into R data structures using the XML package.
The Data Deposit API provides the ability to create and modify Dataverse studies.
