Event Stream Abstraction using Interval Logic

v1.1.3 · Apr 12, 2023 · GPL (>= 3)

Description

This is the R API for the 'nfer' formalism (<http://nfer.io/>). 'nfer' was developed to specify event stream abstractions for spacecraft telemetry such as the Mars Science Laboratory. Users write rules using a syntax that borrows heavily from Allen's Temporal Logic that, when applied to an event stream, construct a hierarchy of temporal intervals with data. The R API supports loading rules from a file or mining them from historical data. Traces of events or pools of intervals are provided as data frames.
