I am surprised to not get a reply.
I suppose this means that extremely few, if any, use rJava.
rJava.pdf says this, but I am too stupid to interpret it:
Description
.jcall calls a Java method with the supplied arguments.
Usage
.jcall(obj, returnSig = "V", method, ..., evalArray = TRUE,
evalString = TRUE, check = TRUE, interface = "RcallMethod",
simplify = FALSE, use.true.class = FALSE)
Perhaps it means that to replace:
calCk <- calStgOfLinTim(linTm,tlev)
and use something like:
calCk <- .jcall(CalqsLin.class,returnSig = "S",
calStgOfLinTim(linTm,tlev),evalArray=FALSE,
evalString = TRUE, check = TRUE, interface = "RcallMethod",
simplify = FALSE, use.true.class = TRUE)
I suppose there are other setup things to do,
like start the JVM (java Virtual machine)
and I don't know what obj means.
Anyway, if I am able to do these simple java method calls,
it will be a big plus to our data analysis lab to use R conveniently.
Please help
