As far as I know, PhreeqC was written in C ++. There is nothing on the USGS website about the R version (see https://www.usgs.gov/software/phreeqc-version-3)

Hi , Dalibor

A Package ‘phreeqc’ has been added to the CRAN warehouse.

https://cran.r-project.org/web/packages/phreeqc/index.html

Thank you for you reply friend

Dear Azzedine,

You can use PHREEQC directly without using any programming language like R, C/C++, etc.

This is much better if you have no previous experience with this software. Moreover, there is a GUI that can help in quickly setting up the models to run. Download and install them from USGS website: https://www.usgs.gov/software/phreeqc-version-3

Scripting PHREEQC with a language like R is possible when one has sufficient experience with the use of the modeling program.

You can find the R interface to PHREEQC here: https://rdrr.io/cran/phreeqc/

It is possible to directly run the distributed PHREEQC examples inside a browser. Here is an example: https://rdrr.io/cran/phreeqc/man/ex1.html

Regards,

Adil
