I found an old windows box, and installed GCDkit: ach, I forgot that there is 
no package dependency management in windows... I fiddled around a bit, I 
installed the latest version of R, which did not work, and finally R-2.7.0, 
then GCDkit2.3_for_R2.7.0. And it works, yes!

RTFM, Pierre. When downloading GCDkit from the website it explicitely telles you which R version to use and even supplies a direct download link :-). This is designed for dumb^w windows users.


I quickly looked across the GCDkit documentation, and it appears that it
is mostly intended for igneous rocks geochemistry.
The plot/profiler gives some good results, but I'd like to mix different
scales (elements vary in very different ranges).
Any idea of which kind of diagrams could be used for my concerns?


Doesn't the profiler allows to select several columns and plot them together ?

Otherwise you'll probably have to use the comand-line interface from within R (that shouldn't be to much of a problem for you), something along the line of

plot(x_from,Au_values,add=TRUE,....).

help(plot) should solve some of your problems I believe.
