The isobxr package is a set of R tools to model the cycling of elements and their stable isotopes in any system of interest.

The program relies on the concepts of stable isotope box-modelling and allows to predict the change with time of isotope ratios in all reservoirs of a system.

This website provides all documentation and tutorials needed to start using isobxr.

News

isobxr 2.0.0 is on CRAN!

Version 2.0.0 of isobxr offers a more efficient and faster data management as well as new tools.

The difference with previous release is available in changelog.

Version 2.0.0 of isobxr is on the CRAN (Comprehensive R Archive Network) and can be found on its isobxr CRAN page.

It can be installed directly from CRAN by calling:

All functions used in 1.0.1 were replaced by new improved functions in 2.0.0 (changelog).

If you need to run former versions of the functions, isobxr 1.0.1 can be installed directly from CRAN archives by calling:

install.packages("https://cran.r-project.org/src/contrib/Archive/isobxr/isobxr_1.0.1.tar.gz", 
                 repos=NULL, 
                 type="source")
