Transform or extract the trajectories from the given object to a standardized format.
The standardized data format is for method estimation by latrend, and for plotting functions.
trajectories(object, ...)# S4 method for data.frame
trajectories(object, id, time, response, ...)
# S4 method for matrix
trajectories(object, id, time, response, ...)
# S4 method for call
trajectories(object, ..., envir)
# S4 method for lcModel
trajectories(object, ...)
The data or model or extract the trajectories from.
Additional arguments.
The identifier variable name.
The time variable name.
The response variable name.
The environment used to evaluate the data object in (e.g., in case object is of type call).
A data.frame with columns matching the id, time, and response name arguments.
