Using this book
0.1 Why should you read this book?
The goal of this bookdown is to provide a complete overview of the theory and methodology of study design for spatial capture-recapture, and to empower our users to confidently generate optimized sampling design for their own use.
0.2 Why should you use
The main function in
oSCR does likelihood analysis of several classes of spatial capture-recapture (SCR) models. There are also a suite of helper functions for formatting and processing data objects. Here are a few of the things that motivated our development of the package:
- 100% native
Rcode, making it (reasonably) accessible to people who know
Rand presumably extensible by ordinary
- Because it’s written in
R, you can look at the code to figure out exactly what’s going on.
- It’s a bit slower compared to
secr, but we think it’s quite robust to massive-sized problems.
- The data structure is relatively simple, just as ordinary
Rlists (for the most part).
- The models accommodate least-cost path models and models that include telemetry data and resource selection functions.
oSCRforces you to define the state-space of the point process which we think is important to understanding an analysis.
0.3 Getting set up
So, using this book of course requires that the
oSCR package is loaded:
But you will also need a few others:
