na.rm

logical, find minimum values instead of maximum ones?

pmin

Combine lists or perform arithmetic operations on elements of lists.

An integrated set of tools for thermodynamic calculations in
aqueous geochemistry and geobiochemistry. Functions are provided for writing
balanced reactions to form species from user-selected basis species and for
calculating the standard molal properties of species and reactions, including
the standard Gibbs energy and equilibrium constant. Calculations of the
non-equilibrium chemical affinity and equilibrium chemical activity of species
can be portrayed on diagrams as a function of temperature, pressure, or
activity of basis species; in two dimensions, this gives a maximum affinity or
predominance diagram. The diagrams have formatted chemical formulas and axis
labels, and water stability limits can be added to Eh-pH, oxygen fugacity-
temperature, and other diagrams with a redox variable. The package has been
developed to handle common calculations in aqueous geochemistry, such as
solubility due to complexation of metal ions, mineral buffers of redox or pH,
and changing the basis species across a diagram ("mosaic diagrams"). CHNOSZ
also has unique capabilities for comparing the compositional and thermodynamic
properties of different proteins.
