CmlMagneville / SmaxN

SmaxN package to compute a new metric of abundance based on a network of cameras

SmaxN

The SmaxN package provides a unique function to compute maximisation of abundances index. It notably helps to compute the Synchronised maxN (SmaxN) based on the use of temporally synchronised cameras.

Installation

You can install the SmaxN package from GitHub with:

## Install < remotes > package (if not already installed) ----
if (!requireNamespace("remotes", quietly = TRUE)) {
  install.packages("remotes")
}

## Install < SmaxN > package from GitHub ----
remotes::install_github("CmlMagneville/SmaxN", build_vignettes = TRUE)

To compute the SmaxN and associated metrics, users need:

• a data frame gathering abundances values through time (rows) and cameras (columns) for the studied species
• a data frame gathering the distance between camera pairs
• the maximal speed of the studied species - established through laboratory experiments, based on field performance or through video measurements if stereo cameras are used
