R interface to geofluidprop

How to use

Unfortunately we are not yey ready to publish a R-package for geofluidprop.
Nevertheless, one can use some functions of geofluidprop from R with the following steps:

1. Build a shared library for R
   This can be done by passing -DBUILD_R_LIB=ON to the cmake arguments. Internally, we use SWIG to generate R interface.
   After running make, the following files will be created under build/lib/r directory.
   • geofluidprop.R
   • geofluidprop.so or geofluidprop.dll

2. Copy all the R related files to your work directory
   Copy the above files and all the R script files under wrapper/R to your work directory for R.

3. Load the wrapper script into R
   In R, move to the work directory and type

    source("geofluidprop_init.R")
   

   This should load the shared library and related wrapper functions. Then, one can type, e.g.,

    water_density <- iapws95_rho_pT(p=1e6, T=293.15)
   

Additional functions in the R scripts

wrapper/R directory includes the following R scripts, that implement additional functions based on geofluidprop functionality:

• H2ONaCl_electrical_conductivity.R: Implementing several formulations to calculate electrical conductivity of H2O-NaCl fluids.
