Overview

About

Maintained by Laura MarshallCRAN page ↗GitHub ↗Issues ↗

Animal abundance estimation via conventional, multiple covariate and mark-recapture distance sampling (CDS/MCDS/MRDS). Detection function fitting is performed via maximum likelihood. Also included are diagnostics and plotting for fitted detection functions. Abundance estimation is via a Horvitz-Thompson-like estimator.

Changes in 3.0.1

Bug Fixes

Fixed formatting issue in flnl.grad help
Fixed output for gof test when degrees of freedom for MR models is <= 0 (Issue #96)
Now displays a warning if the user tries to fit a detection function with covariates using MCDS.exe which is not either a half-normal or a hazard rate model. (Issue #113)
Fixed so that the MCDS.exe does not try to fit a negative exponential in place of a gamme key function. (Issue #113)
Now issues warnings when there is only a single transect and varflag option is 1 or 2. (Issue #115)
No longer plots data points on detection functions for binned analyses, only shows the interval bins.
Add a check and a warning when the object field of the obs.table is not numeric. (Distance Issue #165)

Enhancements

Documentation of dht.se to show variance calculations for varflag options (Issue #117)
Modified the bysample table returned from dht (Issues #60 and #100)
Clarified documentation regarding summary table output from dht.

Install

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

install.packages("mrds", 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("DistanceDevelopment/mrds")

Development version from DistanceDevelopment/mrds. 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-mrds

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-mrds

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-mrds

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.
