Thanks Eric, I saw that page, too, but it states: "This post describes how to pass external arguments to R when calling a Rscript with a command line." Not what I'm trying to do.

That's amazing! Thank you!!! One follow up question, if that's OK? If, instead of using hard-coded CSV, I read the CSV into a variable first, then it fails again with a parse error. Code below. So, if I read the CSV into a variable, do I need an additional wrapper method? Seems like it should still work. Thanks in advance for your reply. -M String inputIris =

I do not program in Java but it seems a Java program can make system calls which would be equivalent to running from the command line, but done from within a Java program. Not sure whether that would meet your needs and if not why not. Just a suggestion.

It can't be this hard, right? I really need a shove in the right direction here. Been spinning wheels for three days. Cannot get past the errors. I'm doing something wrong, obviously, since I can easily compute the Box's M right there in RStudio But I don't see what is wrong below with the coding equivalent. The entire code snippet is below. The code fails below on the call to

I'm not sure what you mean. Could you please be more specific? If I print the string, I get: boxM(boxMVariable[, -5], boxMVariable[, 5]) From this code: . . . // assign the data to a variable.rConnection.assign("boxMVariable", myDf); // create a string command with that variable name.String boxVariable = "boxM(boxMVariable[, -5], boxMVariable[, 5])";

Thanks Duncan. Awesome ideas! I think we're getting closer! I tried what you suggested and got a possibly better error... . . . rConnection.assign("boxMVariable", myDf); String resultBV = "str(boxMVariable)"; // your suggestion. RESULTING ERROR: Error in format.default(nam.ob, width = max(ncn), justify = "left") : invalid 'width' argument (No idea

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

Hey Duncan, Hard to debug? That's an understatement. Eyes bleeding.... In any case, I tried all your suggestions. To get "integer" for the final column, I had to change the code to get integers instead of strings. double[] d1 = ((REXPVector) ((RList) tableRead).get(0)).asDoubles(); double[] d2 = ((REXPVector) ((RList) tableRead).get(1)).asDoubles(); double[] d3 = ((REXPVector)

Thanks Duncan. I can't tell you how helpful all your terrific replies have been. I think the biggest surprise is that nobody appears to be using Java and R together like I"m trying to do. I suppose it should be a surprise since there are no books on the subject and almost no technical documentation other than a few sites here and there. ----- I originally had the "int" as the

Hello All, Although running Java from R used to work, for some mysterious reason, it's stopped. Today when I tried to load a basic JDBC driver (or the sample .jinit()) code, I got: - JavaVM: requested Java version ((null)) not available. Using Java at "" instead. - JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib - JavaVM FATAL: Failed to load the jvm library. I

Is it possible to pass parameters to an R Script, say, from Java or other language? I did some searches, but came up blank. Thanks very much in advance, Sent from [ProtonMail](https://protonmail.com), Swiss-based encrypted email. [[alternative HTML version deleted]]

Trying to get past a frustrating error to do a "simple" Box's M test using Java. The Box's M test says it will work with a data.frame. Here's the setup code: REXP myDf = REXP.createDataFrame(new RList( new REXP[] { new REXPDouble(d1), new REXPDouble(d2), new REXPDouble(d3), new REXPDouble(d4), new REXPInteger(d5) })); Here's the call: REXP boxMResult =

Hi All, OK, in the "back to the drawing board" department, I found what looks like a much better solution to using R in Java. Renjin. Looking at the docs and then trying a quick example, didn't quite work. Of course I'm missing something. Although I'm telling the engine to require ("biotools") just like I would in R itself, when I get to the line of code that

Hey Duncan, Since Java is the #1 language and R is extremely popular, I think the most telling thing is that nobody on the "R-devel" forum (where people do "programming with R") is doing R and Java like I'm doing: calling R from Java and passing data structures. So it appears I'm clearly pushing R somewhere it doesn't want to go. And, the boxM issue is more or

I asked this question yesterday, but since I didn't receive any responses, I thought I would simply the question a bit and try again. Basically, I'm getting a query result sent to a program. That data is just the rows and columns of a database table. Simple 2-D. My (hopefully simple) question is how do I take that variable and put that two-dimensional data in a form I can then send to R?

Thanks for the quick responses. As you both suggested storing the packages to local drive is feasible but comes with a size restriction I wanted to avoid. I'll keep this in mind as plan B. @Hugh: 2. would impose even greater slowdowns and 4. is just not feasible. However, 3. sounds interesting - how would this work in a Linux environment?

I realize the communication between R and Java with Rserve in my dissertation, but i can not run the Rserve by double click of Rserve.exe, and also i can't realize backstage running of Rserve by technique of Multi-thread in Java. Can anyone tell me why? So, before i run the Java, i must run the R manually, then input "Rserve()" or "system("Rserve")". This

I want to use the R functionalities in my Java program. I found the Rserve that appear to suite my requirements but I'm facing some configuration problems. I' following the web page tutorial (http://stats.math.uni-augsburg.de/Rserve/doc.shtml) but I face the above problem: C:\Program Files\R\rw2010\bin>R CMD RSERVE Can't open perl script "C:\PROGRA~1\R\rw2010/bin/RSERVE":
