GCDkit is one of the most versatile packages for igneous petrology. Writing scripts in 'r' for GCDkit has a steep learning curve. Tutorials may help to facilitate learning with feedback.

Thank you for the information and links, Subhojit Saha and Edward Osario.
You may also consider a brand new book dealing with interpretation of whole-rock geochemical data using R/GCDkit, just out:

Dear M Ghoneim,
Can you specify the type of binary diagram you need to draw (with the log scale)? If you are working with GCDKit, you can use the GCDKit cheat sheet or manual for reference. You can use the GCDKit blog site for some good tutorials for binary plots: http://www.gcdkit.org/. Otherwise you can also refer the freely available excel sheets from here: https://www.geoplotters.com/find-a-plot. There are plots which use log scales and you can fit in your data in a blank log scaled plot. You can add the fields later. Hope this helps.
M.Jayabalan.
Dear M. Ghoneim,
In GCDkit, you can simply use the menu Plots|Binary plot, and when asked to specify which of the axes should be logarithmic, reply x, y, or xy. See also indication in the relevant dialogue box.
Best wishes, Vojtech Janousek
Hello,
the GCDkit programme can be, together with all relevant documentation pertaining to your questions, downloaded from the home page of the project, gcdkit.org. No, me creating a Russian version of the GCDkit is extremely unlikely, as I have other priorities.

I advise you to join the GCDkit forum at http://blog.gcdkit.org/
Cheers!

Thank you, Marco. I have visited the blog sometime back and have found it quite useful. I will consider joining the blog after I get some expertise with the r language. The learning curve is reasonably steep.
