tr1

An object of class Track.

tr2

An object of class Track.

• A difftrack object. Includes both tracks extended with additional points for the timestamps of the other track. Also includes SpatialLines representing the distances between the tracks.

Examples

## example tracks
library(sp)
library(xts)
data(A3)
track2 <- A3
index(track2@time) <- index(track2@time) + 32
track2@sp@coords <- track2@sp@coords + 0.003

## compare and plot
difftrack <- compare(A3, track2)
plot(difftrack)
