spatsoc is an R package for detecting spatial and temporal groups in GPS relocations. It can be used to convert GPS relocations to gambit-of-the-group format to build proximity-based social networks with grouping and edge-list generating functions. In addition, the
randomizations function provides data-stream randomization methods suitable for GPS data and the
get_gbi function generates group by individual matrices useful for building networks with
For more details, see the blog post and vignettes:
We wrote a
targets workflow, available at github.com/robitalec/targets-spatsoc-networks.
targets is an incredible package for designing workflows in R and, with it, we can reproducibly run all steps from raw telemetry data to output networks and metrics. Check it out and let us know how it works for you!
Edge-list generating functions added:
and dyad id function:
(feedback welcome as always!)
Both documented further in a vignette: Using edge list and dyad id functions.

# Stable release install.packages('spatsoc') # Development version remotes::install_github('ropensci/spatsoc')
spatsoc depends on
rgeos and requires GEOS installed on the system.
apt-get install libgeos-dev
pacman -S geos
dnf install geos geos-devel
brew install geos
- Windows: see here
spatsoc expects a
data.table for all of its functions. If you have a
data.frame, you can use
data.table::setDT() to convert it by reference. If your data is a text file (e.g.: CSV), you can use
data.table::fread() to import it as a
group_times groups rows temporally using a threshold defined in units of minutes (B), hours (C) or days (D).
group_pts groups points spatially using a distance matrix (B) and a spatial threshold defined by the user (50m in this case). Combined with
group_times, the returned ‘group’ column represents spatiotemporal, point based groups (D).
group_lines groups sequences of points (forming a line) spatially by buffering each line (A) by the user defined spatial threshold. Combined with
group_times, the returned ‘group’ column represents spatiotemporal, line overlap based groups (B).
group_polys groups home ranges by spatial and proportional overlap. Combined with
group_times, the returned ‘group’ column represents spatiotemporal, polygon overlap based groups.
edge_nn generate edge-lists.
edge_dist measures the spatial distance between individuals (A) and returns all pairs within the user specified distance threshold (B).
edge_nn measures the distance between individuals (C) and returns the nearest neighbour to each individual (D).
