Contributed R Packages

Below is a list of all packages provided by project CHNOSZ.

Important note for package binaries: R-Forge provides these binaries only for the most recent version of R, but not for older versions. In order to successfully install the packages provided on R-Forge, you have to switch to the most recent version of R or, alternatively, install from the package sources (.tar.gz).



Thermodynamic Calculations and Diagrams for Geo(bio)chemistry

  An integrated set of tools for thermodynamic calculations in geochemistry and compositional biology. The thermodynamic properties of liquid water are calculated using Fortran code from SUPCRT92 (Johnson et al., 1992 ) or an implementation in R of the IAPWS-95 formulation (Wagner and Pruß, 2002 ). Thermodynamic properties of other species are taken from a database for minerals and inorganic and organic aqueous species including biomolecules, or from amino acid group additivity for proteins (Dick et al., 2006 ). High-temperature properties are calculated using the Berman-Brown (1985) equations for minerals and the revised Helgeson-Kirkham-Flowers (1981) equations for aqueous species. The HKF equations are augmented with the Deep Earth Water (DEW) model (Sverjensky et al., 2014 ) and estimates of parameters in the extended Debye-Hückel equation (Manning et al., 2013 ) to calculate standard-state properties and activity coefficients for given ionic strength at high pressure (to 6 GPa). Functions are provided to calculate standard-state properties of species and reactions, define the basis species of a chemical system, automatically balance reactions, calculate the chemical affinities of formation reactions for selected species, calculate the equilibrium activities of those species, and plot the results on chemical activity diagrams.

Build status codes

0 - Current: the package is available for download. The corresponding package passed checks on the Linux and Windows platform without ERRORs.
1 - Scheduled for build: the package has been recognized by the build system and provided in the staging area.
2 - Building: the package has been sent to the build machines. It will be built and checked using the latest patched version of R. Note that it is included in a batch of several packages. Thus, this process will take some time to finish.
3 - Failed to build: the package failed to build or did not pass the checks on the Linux and/or Windows platform. It is not made available since it does not meet the policies.
4 - Conflicts: two or more packages of the same name exist. None of them will be built. Maintainers are asked to negotiate further actions.
5 - Offline: the package is not available. The build system may be offline or the package maintainer did not trigger a rebuild (done e.g., via committing to the package repository).

If your package is not shown on this page or not building, then check the build system status report.
