Overview

About

Maintained by Matthew KlingCRAN page ↗GitHub ↗Website ↗Issues ↗

Provides an R-native interface to the 'Circuitscape.jl' and 'Omniscape.jl' 'Julia' packages for landscape connectivity modeling using circuit theory. Users work entirely in R with familiar objects (SpatRaster, file paths) while 'Julia' handles computation invisibly. Supports all four 'Circuitscape' modes (pairwise, one-to-all, all-to-one, advanced) and 'Omniscape' moving-window analysis. Methods are described in McRae (2006) doi:10.1111/j.0014-3820.2006.tb00500.x and Landau et al. (2021) doi:10.21105/joss.02829.

Changes in 0.1.1

New features

New os_condition() constructor gives os_run() full access to Omniscape's conditional connectivity (#2):
"within" comparisons with user-specified bounds (lower, upper).
Present-vs-future comparisons (future), in which sources' present-day values are compared against targets' future values, as in climate-tracking connectivity analyses.
Two simultaneous conditions, by passing a list of two os_condition() objects.
os_run() now warns when a condition layer has missing values at source cells, which Omniscape does not filter.
All cs_*() functions and os_run() now warn if the installed Circuitscape.jl or Omniscape.jl does not recognize a configuration option written by circuitscaper, rather than letting the option silently have no effect.

Bug fixes

In 0.1.0, os_run()'s condition_type argument was written to the Omniscape configuration under a key Omniscape does not recognize, so it was silently ignored. All conditional analyses instead used Omniscape's defaults, "within" with bounds of 0 and 0: a source was connected to a target only if its condition value exactly equaled the median value of the target block. This was neither the documented behavior (an unbounded range) nor the requested "equal" comparison. **Results from 0.1.0 that used condition should be rerun.**
In 0.1.0, four_neighbors = TRUE was written to the Circuitscape configuration under an unrecognized key and silently ignored in cs_pairwise(), cs_one_to_all(), cs_all_to_one(), and cs_advanced(); all analyses used 8-neighbor connectivity. **Results from 0.1.0 that used four_neighbors = TRUE should be rerun.**

Breaking changes and deprecations

Passing a raster directly as os_run(condition = ) is now shorthand for os_condition(x, type = "equal"). Use os_condition() for "within" comparisons, which now require explicit bounds.
os_run()'s condition_type argument is deprecated. condition_type = "equal" still works with a warning; condition_type = "within" now errors, since it has no way to specify bounds.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("circuitscaper", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("matthewkling/circuitscaper")

Development version from matthewkling/circuitscaper. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-circuitscaper

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-circuitscaper

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-circuitscaper

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
