Plot the data trajectories

Plots the output of trajectories for the given object.

plotTrajectories(object, ...)

# S4 method for class 'data.frame'
plotTrajectories(
  object,
  response,
  cluster,
  time = getOption("latrend.time"),
  id = getOption("latrend.id"),
  facet = TRUE,
  ...
)

# S4 method for class 'ANY'
plotTrajectories(object, ...)

# S4 method for class 'lcModel'
plotTrajectories(object, ...)

Arguments

object

The data or model or extract the trajectories from.

...

Additional arguments passed to trajectories.

response

Response variable character name or a call.

cluster

Whether to plot trajectories grouped by cluster (determined by the "Cluster" column). Alternatively, the name of the cluster column indicating trajectory cluster membership. If unspecified, trajectories are grouped if the object contains a "Cluster" column.

time

The time variable name, see timeVariable.

id

The identifier variable name, see idVariable.

facet

Whether to facet by cluster.

Examples

data(latrendData)

if (require("ggplot2")) {
  plotTrajectories(latrendData, response = "Y", id = "Id", time = "Time")

  plotTrajectories(
    latrendData,
    response = quote(exp(Y)),
    id = "Id",
    time = "Time"
  )

  plotTrajectories(
    latrendData,
    response = "Y",
    id = "Id",
    time = "Time",
    cluster = "Class"
  )
}

data(latrendData)
method <- lcMethodLMKM(Y ~ Time, id = "Id", time = "Time")
model <- latrend(method, latrendData, nClusters = 3)

if (require("ggplot2")) {
  plotTrajectories(model)
