README
This README would normally document whatever steps are necessary to get this application up and running.
What is this R package for?
-
Statistical modeling of animal movements in R. Statistcal models in reference are provided by this package. They are moving-resting model with embedded Brownian motion^[1,2], moving-resting-handling model with embedded Brownian motion^[3], Brownian motion with measurement error^[4], moving-resting model with measurement error^[5], moving-moving model with two embedded Brownian motions. A quick guide for this package is given as package vignette.
-
Version: 0.7.1
How do I get set up?
- Run the following R code.
## install.packages("devtools")
devtools::install_github("ChaoranHu/smam")
or
install.packages("smam")
Note: The first way allows you to access to the most recent version of this package but it also requires development toolbox. This package includes Cpp and C codes, so you need a CPP compiler (for mac, you can use Xcode, which can be installed from Apple Store). Also, this package uses GNU GSL, so you need to install GNU GSL first. If you do not have these tools, you could use second way to install from CRAN.
- Run
library(smam)to load in R.
How do I use?
Please read the vignette of this package for more information, documentation and examples.
