Extracting regression coef. and p-values in JRClient
...ols/R/D2R1.txt\",header=T,sep=\",\")");
c.eval("result <- glm(Nausea ~ Kaletra*Sustiva, family =
binomial(link = logit), data =KSN)");
I can obtain the coef. using:
REXP coeffExp = c.eval("coefficients(result)");
double[] coeff = coeffExp.asDoubleArray();
how could I transfer the p-values, i.e., Pr (>|z|), for each coef., in
java vector, based on the variable 'result'.
Thanks.

RServe
Dear all,
I'm trying to use R-functions from Java. I want to use the Package Rserve.
Everthing is installed and I can run my Java-testprogramm.
...
Rconnection r = new Rconnection();
double[] d = r.eval("rnorm(10)").asDoubleArray();
...
But now I get always arrays with ten "0.0", which is not correct
I suppose, that is is a problem from R, because at the fist time (last week)
I started RServe I got an icon in my taskbar which was something about a R
server. But I never got it since then...
I tried to reinstall R...

Problem with calling an user defined R function from Java
...oject_WRAIR/US09493743_251527910706_1_1 T10-105_5day_24hrs";
//where data is the input.
re.eval("source('C:/Project_WRAIR/Normalisation.r')");
System.out.println(re);
REXP rn = re.eval("my.Normal(data)");
System.out.println(rn);
double[] rnd = rn.asDoubleArray();
for(int i=0; i<rnd.length; i++){
System.out.print(rnd[i] + " ");
}
This gves an NullPointerException and on printing the variable rn, we get
null as the output.
Please do suggest a way out.
Thanks in advance.
