No answer to my post, so let's try a simpler question. Am I doing this correctly? I have the RGui with R Console on the screen. On rhe top pullDowns, Packages > Install Packages > USA(IA)> rJava > library(rJava) > .jinit() > qsLin <- .jnew("C:/ad/j/CalqsLin") Error in .jnew("C:/ad/j/CalqsLin") : java.lang.NoClassDefFoundError: C:/ad/j/CalqsLin
So I got this error which means I don't understand very much. I go to C:/ad/j and get C:\ad\j>dir CalqsLin.class Volume in drive C has no label. Volume Serial Number is 9A35-67A2 Directory of C:\ad\j 04/23/2011 07:11 AM 14,651 CalqsLin.class 1 File(s) 14,651 bytes 0 Dir(s) 104,257,716,224 bytes free Just to show my intentions, I had next wanted to call this java function method: linTimOfCalqsStgIsLev("201104052359599999",-4) using: > dblTim <- > .jcall(qsLin,"D","linTimOfCalqsStgIsLev","201104052359599999","-4") but that will probably also be wrong? Obviously I don't understand. -- View this message in context: http://r.789695.n4.nabble.com/Using-Java-methods-in-R-tp3469299p3469848.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
