Chunk Gazepoint biometric data into fixed analysis episodes — chunk_gazepoint

Adds programmatic fixed-duration chunks/episodes to continuous biometric data. This is useful for baseline segmentation, repeated-measures feature extraction, and analyses that do not rely on external TTL markers.

Usage

chunk_gazepoint_biometrics(
  dat,
  time_col = "CNT",
  group_cols = NULL,
  chunk_seconds = 60,
  start_time = NULL,
  chunk_col = "chunk_id",
  episode_col = "episode_id",
  include_partial = FALSE
)

Arguments

dat: A data frame.
time_col: Numeric time column.
group_cols: Optional grouping columns.
chunk_seconds: Chunk duration in seconds.
start_time: Optional fixed start time. If NULL, uses group minimum.
chunk_col: Output chunk identifier column.
episode_col: Output episode label column.
include_partial: Logical. If FALSE, partial final chunks are marked but not assigned as complete chunks.

Value

A data frame with chunk columns and chunk-summary attributes.
