Reads river network shape files and computes network distances. Also included are a variety of computation and graphical tools designed for fisheries telemetry research, such as minimum home range, kernel density estimation, and clustering analysis using empirical k-functions with a bootstrap envelope. Tools are also provided for editing the river networks, meaning there is no reliance on external software.

The riverdist package provides tools for distance calculation along a river network. The river network is imported from a projected shapefile. Spatial point data may be imported from a shapefile as well, or directly from coordinates.
Some basic formatting of the river shapefile may be necessary. If available, formatting in a geographic information system (GIS) prior to importing into R is recommended (projecting, spatial trimming to the study area, and possibly dissolving river segments), but the riverdist package and its dependencies also include tools for accomplishing the necessary formatting within R.
