feedr

feedr processes time-stamped, georeferenced detections from RFID and other stationary loggers to transform and visualize animal movement patterns for studies of habitat use, resource use, and social interactions.

Key Features:

• R package implementation: Provided as an R package for programmatic data loading, transformation, and visualization workflows.
• Data transformation: Converts raw RFID and stationary-logger detections into visits, presence (regular detections over time), movements between loggers, displacements, and activity patterns.
• Integration with other R packages: Includes conversion functions to format data for compatibility with complementary R packages.
• Visualization capabilities: Produces static and interactive map visualizations and time-based animations of detections and movements.
• Supported data sources: Handles data from RFID static logger stations and other stationary sources such as hair traps, static VHF telemetry loggers, and observations of marked individuals.

Scientific Applications:

• Animal movement analysis: Quantifies movements between logger locations and patterns of site visitation.
• Habitat and resource use: Infers habitat or resource-use patterns from spatially and temporally resolved detections.
• Social interaction inference: Identifies co-occurrence and temporal overlap at logger sites to support analyses of social interactions.
• Colony and staging-site monitoring: Analyzes detections of marked individuals at colonies or staging sites to monitor presence and turnover.

Methodology:

Processes time-stamped georeferenced detections from static logger stations; transforms raw detections into visits, presence, movements, displacements, and activity patterns; provides data-format conversion functions for other R packages; and generates static/interactive maps and time-based animations.
