Description Usage Arguments Value Examples

calculate square displacement of a track/trajectory as a function of time/step. data.frame has two column, x and y also calculate dx, dy bivariate squareDispCpp is the cpp version of squareDisp

1 2	squareDisp(track,dt=1,resolution=0.107) squareDispCpp(track,dt=1,resolution=0.107)

`track`	track dataframe with x and y coordinates.
`dt`	time step size(in frames).
`resolution`	resolution value, default is 0.107.

list of square displacements(dx^2 + dy^2) for varying dt values from 1 to dt
