spatsoc

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 asnipe::get_network.

See below for installation and basic usage.

For more details, see the blog post and vignettes:

News

New edge-list generating functions added (feedback welcome as always!):

  • edge_nn
  • edge_dist

Installation

Install the latest version with remotes.

remotes::install_github('ropensci/spatsoc')

# or CRAN
install.packages('spatsoc')

spatsoc depends on rgeos and requires GEOS installed on the system.

  • Debian/Ubuntu: apt-get install libgeos-dev
  • Arch: pacman -S geos
  • Fedora: dnf install geos geos-devel
  • Mac: brew install geos
  • Windows: see here

Usage

Load package, import data

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 data.table.

library(spatsoc)
library(data.table)
DT <- fread(system.file("extdata", "DT.csv", package = "spatsoc"))
DT[, datetime := as.POSIXct(datetime, tz = 'UTC')]

Functions

spatsoc provides:

one temporal grouping function,

  • group_times

three spatial grouping functions,

  • group_pts
  • group_lines
  • group_polys

two edge-list generating functions,

  • edge_nn
  • edge_dist

and two social network analysis functions.

  • randomizations
  • get_gbi
