Hello everyone

I was wondering if it was possible to call the function of the R software into JForex.

Any suggestions?

If it is a java library then see:
https://www.dukascopy.com/wiki/#Include_libraries
Otherwise, consider using jna (attach the jna.jar file as a library):
https://github.com/twall/jna
Or find a java library which implements the functionality that you need.

also see JRI, it's a small java library included in rJava R package
but I didn't manage to get there example working yet

@Support, I guess it would work with local run if we have R installed, but it wouldn't work in backtests, since you probably don't have R installed and configured on your backtest servers?

No, libraries should in all run modes - Local Run, Remote Run, and when back-testing.
