Calculates expected displacement for a given SDR and time span
get_displacement(delta, time_span)Returns a numeric vector (of length 1) with the expected displacement in meters.
[numeric] A squared displacement rate (SDR), such as that
returned by calculate_sdr(). Units assumed to be m^2/s.
[Period] A lubridate Period giving the time span
for which to calculate expected displacement.
