Fetching Warning Messages
Hi,
I am facing one problem of fetching R warning messages in Java Code
using Rserve. It is easier to trap R Error messages by using catching
RSrvException. I came to know one way of fetching R Warning messages, i.e.
using "withCallingHandlers", below is my Java Program, which uses
withCallingHandlers of R :
import org.rosuda.JRclient.*;

You were trying to eval an expression that you constructed in Java. I
was suggesting that before you eval it, you print it.

Does it work if you supply the closing parenthesis on the call to boxM?
The parser says the input is incomplete and a missing closing parenthesis
would cause that error..
// create a string command with that variable name.String boxVariable =
"boxM(boxMVariable [,-5], boxMVariable[,5]";
// try to execute the command...

How to create a table structure in Java code?
I suspect that you are looking for something like:
read.csv(textConnection(
"5.1,3.5,1.4,0.2,setosa
4.9,3,1.4,0.2,setosa
4.7,3.2,1.3,0.2,setosa
4.6,3.1,1.5,0.2,setosa
5,3.6,1.4,0.2,setosa"
), header = FALSE)

How to create a table structure in Java code?
You are entering the quoting hell - you are missing quotes and escapes for \n. it would be much more reasonable to use the rConnection.assign method instead of pasting any content through the parser.

How to efficiently share data (a dataframe) between R and Java
You can pass the entire df, example:
> data(iris)
> iris$sp = as.character(iris$Species)
> o=.jarray(lapply(iris, .jarray))
> .jcall("C",,"df",o)
df, 6 variables
[0]: double[150]
[1]: double[150]
[2]: double[150]
[3]: double[150]
[4]: int[150]
[5]: String[150]
Java code:
public class C {

How to create a table structure in Java code?
Thanks! I just figured it out (thanks to "Beyond Compare") and was coming here to post back.
The boxM test doesn't work with that (now, finally working) REXP structure, but I probably now need to create a table or something and parse that structure.
So much fun! :)
Thanks again.

The last column in iris is actually a factor. That's stored as an

Just print the string you are asking to R to evaluate. It doesn't make
any sense as an R expression. Fix that, and things will work.

How to create a table structure in Java code?
Hi all,
Using RConsole, it's easy to get data from the database that you can use in an R Command. Like this:
(Reference case)
irisQuery <- dbGetQuery(conn, "select * from iris")
boxM(irisQuery [,-5], irisQuery[,5])
----
(Actual case this posting is about)
Yet, if I'm getting that same (sample IRIS) data, say, in a web service possibly POSTED from a SQL command, that same

[LLVMdev] Alternative exception handling proposal
Hi Bill, there is clearly a misunderstanding: either I am missing something

am indeed failing to see something).

Handling warning messages
Hi,
I have query regarding R & Rserve. In Rserve, there is a way to capture
Errors by RSrvException class, but is there any way to capture warning
messages?
I have found that there is "warnings()" command in R, which lists the
last warning message, but I am not able to get the warning message in java
program by executing the following line:
