movement(
  x = stop("data.frame must be provided"),
  col.time = "Time",
  col.x = "x",
  col.y = "y",
  col.z = "z",
  NumberRecordBeforeEmergence = 1900,
  k = 4,
  Windowsize = 15
)

Value

The function will return a list

A data.frame with 4 columns, one for time and three for x, y, and z position

col.time

Name of the column with time

col.x
