Welcome to simmr!
simmr is a Bayesian stable isotope mixing model implemented in R which also uses JAGS. It is intended as a replacement to the SIAR package.
If you want the official stable version of the package from CRAN then go to R and type:
install.packages('simmr')
You can then load the package and view either the quick start or the full user manuals with:
library(simmr)
vignette("simmr")
vignette("quick_start")
Alternatively you can install the latest development version of the package in R with the commands:
if(!require(remotes)) install.packages('remotes')
remotes::install_github('andrewcparnell/simmr')
You can then load the package with
library(simmr)
... and look at the user manuals via:
vignette('simmr')
vignette('quick_start')
vignette('advanced_plotting')
