Set metadata

Source: R/metadata_set.R
set_metadata.Rd

Sets or updates metadata for an aniframe or anievent object. Metadata can be provided either as named arguments or as a list. If the object already has metadata, the new values will be merged with existing values, with new values taking precedence.

Character values for factor fields will be automatically converted to factors if they match allowed levels.

Default metadata fields include:

  • source: Data source identifier

  • source_version: Version of the data source

  • filename: Original filename(s) — accepts a character vector (length 1 or more) for readers that load from multiple files

  • sampling_rate: Sampling rate in Hz

  • start_datetime: Start date and time of recording

  • reference_frame: Reference frame (default: "allocentric")

  • coordinate_system: Coordinate system (default: "cartesian")

  • origin: Location of the (0,0) coordinate (default: "bottom_left")

  • y_height: Height of the recording frame in y-axis units (default: NA)

For backwards compatibility, the deprecated field point_of_reference is accepted as an alias for origin and emits a deprecation warning.

Usage

set_metadata(data, ..., metadata = NULL)

Arguments

data

An aniframe or anievent object.

...

Named metadata values (e.g., sampling_rate = 30, source = "sleap")

metadata

Alternatively, a named list of metadata. Cannot be used simultaneously with ...

Value

The object with updated metadata.
