+This vignette shows how to use parallelization on a data set containing a set of animals weighted over time with the walk-over-weighing system. 
+The `lambs` data set is included in the **kfino** package and can be loaded using the `data()` function.

+We use the **parallel** and **doParallel** libraries to accelerate the computing time.
