dssd

Distance Sampling Survey Design

dssd is a package for designing distance sampling surveys. It provides a number of designs including systematic point transect, parallel line transect, zigzag line transect and segment line transect designs.

Using dssd

There are two vignettes within the dssd package to help you get started using dssd:

  • GettingStarted: "Getting Started with dssd"
  • MultiStrataVignette: "Multiple Strata in dssd"

Getting dssd

The easiest way to get dssd is to install it from CRAN within R-studio or the R interface. We endeavour to make all new functionality available on CRAN in a timely manor. However, if you wish to download the development version with the latest updates immediately you can do this using Hadley Wickham's devtools package:

  install.packages("devtools")

then install dssd from github:

  library(devtools)
  install_github("DistanceDevelopment/dssd")
