[R] Problem:: Passing r list to java method as parameter
Hi Simon,
I have some doubts in the function calling R. I am using the R 2.9.1 with
window XP.
I am passing the r list to the java method as a parameter. And then try to read
this r list from java code.
Is it possible that we can read the r list into the java code? My script and
code are given below.
setBTE<- function(...)
{
propString=match.call(expand.dots=F);
propList=propString$...;
propList
library(rJava)
.jinit(classpath="BTEApp.jar", parameters="-Xmx1100m")
.jaddClassPath("/lib/commons-lang-2.0.jar")
.jaddClassPath("/lib/jcommon-1.0.10.jar")
.jaddClassPath("lib/jfreechart-1.0.6.jar")
.jaddClassPath("/lib/jtds-1.2.jar")
.jaddClassPath("/lib/log4j.jar")
.jaddClassPath("/lib/util.jar")
.jaddClassPath("/lib/JRI.jar")
ss<-.jnew("com/bte/gui/HomePageBTE")
.jcall(ss, "V", "initBTE", propList, check=FALSE)
}
My Java code is like:
public void initBTE(RList propertyList)
{
bteLog.info("Calling The initBTECall method:");
String[] k = propertyList.keys();
if (k!=null)
{
int i=0;

Re: [R] FW: Qury Related With R
Hi Romain,
Attached is my R script that script I put into the R work space and
through source("RScriptToCallJava.R") command I call the script and my java
application is execute.
Is it the proper way to call the java application? If not, then please
can you explain the directory structure that needs for java application?
In java I used the property file. but when I load the property file using
.jaddClassPath("D:/R_BTE_Jar/BTE/app.properties") command, it is not load.
Thanks Romain for your response.

Hi,
The file did not make it through the mailing list. Maybe you are looking
for ?read.dcf
Can you describe the way your application interacts with R.

Re: [R] FW: Qury Related With R
Hi Romain,
Exactly this is the script which I need. Thanks a lot for helping.
Romain, Is there any way to modified a particular line in the property
file through R script? If yes then please explain how.
Cheers!

Hi,
I think you can just do something like read the parameters into R, and
then use the "parameters" argument of the .jinit function. Something
like this perhaps:
props <- readLines( "app.properties" )
props <- strsplit( gsub( "\\\t", "", grep( "=", props, value = TRUE )
), "=" )
params <- sapply( props, function(x){
sprintf( "-D%s=%s", x[1], x[2] )
} )
library(rJava)
.jinit(classpath="D:/R_BTE_Jar/BTE/BackTestingApp.jar",
parameters= c( "-Xmx512m", params ) )
Let me know if this works.

Hi Simon,
Now I am able to connect my SQL Server2000 from R using RODBC as you told me

I suspect that you'll need to load the corresponding drivers. The
message essentially tells you that the driver (class) you're trying to
load is not known. I don't use Windows (and even less so SQL Server),
so I'd suggest you search for JDBC and MS SQL Server and/or ask on the
SIG-DB mailing list (although this is technically not an R question).
With some luck there may be some MS SQL users on this list as well..
However, if you are on Windows, you may want to go directly to ODBC
using RODBC instead of going through JDBC.
Cheers,
Simon
