trajectories | R Documentation |
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,
id = idVariable(object),
time = timeVariable(object),
response = responseVariable(object),
...
)
## S4 method for signature 'data.frame'
trajectories(

## S4 method for signature 'matrix'
trajectories(
