 Now that this casualty data has been cleaned, subsetted (to only include serious cycle crashes) and converted into a spatial class system, we can analyse them using geographical datasets of the type commonly used by **stplanr**.
-The following code, for example, geographically subsets the dataset to include only crashes that occured within the bounding box of a [route network dataset](https://github.com/ropensci/stplanr/blob/master/data/route_network.rda?raw=true) provided by **stplanr** (from version 0.1.7 and beyond) using the function `bb2poly`, which converts a spatial dataset into a box, represented as a rectangular `SpatialPolygonsDataFrame`:
