Hello,
I am a new R user. More precisely, I am working with JRI (on a Eclipse
Java6 project under Ubuntu9).
I have difficulties to access some R packages (For example: package
"stats", object "Normal", function "pnorm").
I have tried many solutions to set the right path but nothing have succeed:
For example: LD_LIBRARY_PATH=${R_HOME}/lib:${R_HOME}/bin:${R_HOME}/library
Inside the java code, I have also tried such methods:
Note that "r" is the REngine object coming from the connection to R
r.eval("dyn.load(\"/home/gran/workspace/R-2.9.0/library/stats/libs/stats.so\",
local = TRUE, now = TRUE)");
r.eval("require(stats)");
r.eval("autoload(\"Normal\", \"stats\")");
r.eval("search()");
r.eval("ls(\"Autoloads\")");
System.out.println(r.eval(".Autoloaded"));
r.eval("zval = .95");
System.out.println(r.eval("print(zval)"));
r.eval("p3 = pnorm(3*zval)");
System.out.println(r.eval("print(p3)"));
It gives as a result:
[STRING "stats"]
[REAL* (0.95)]
null <---------- p3 = null because pnorm is unknown
Do you know how to use the "stats" package with JRI ?
Thanks in advance,
Antoine
