Hi, I'm Angel Orosa Rodríguez again, I've sent an email in Spanish explaining my problems; here is the same problems but in English, of course. Well, I'm developing an application in Java but I need to call an R program; I've looked for something that I can use for it and I found JRI; when I was trying to install it, I needed to use "sh" command in windows but I hadn't got it installed; I read in Internet that I'll need two things: - MinGW: I've found and installed it, but nothing appears and I'm not able to use sh yet. - /bin toolset: I don't know what it is and how can I obtain it. On the other hand I was investigating about JRI and I don't know if I will can use it because I need to call a program file in R and I don't know if it is posible with JRI. There is another way to do it?? Thanks for your attention!!! I would be very grateful if you can help me. -- Ángel Orosa Rodríguez [[alternative HTML version deleted]]
