prepare_trajectory_data: Prepares trajectory data for an ENA plot.

In rENA: Epistemic Network Analysis

Prepares trajectory data for an ENA plot.

Description

This function processes and prepares trajectory data for plotting in an ENA set. It handles rotation, grouping, and filling missing steps in the trajectory.

Usage

prepare_trajectory_data(
  x = NULL,
  by = x$`_function.params`$conversation[1],
  rotation_matrix = x$rotation.matrix,
  points = NULL,
  units = points,
  units_by = x$`_function.params`$units,
  steps = NULL
)

Arguments

x	An ENA set object. If 'NULL', other parameters must be provided.
by	A character vector specifying the grouping variables for the trajectory. Default is the first conversation parameter in the ENA set.
rotation_matrix	A matrix used to rotate the points. Default is the rotation matrix from the ENA set.
points	A data table of points to be processed. Default is the points from the ENA set.
units	A data table of units corresponding to the points. Default is the trajectories or points from the ENA set.
units_by	A character vector specifying the unit grouping variables. Default is the unit parameters from the ENA set.
steps	A data table specifying the steps for the trajectory. If 'NULL', steps are generated automatically.

Value

A data table containing the processed trajectory data, including dimensions and metadata.
