similar to: Box's M test

Hopefully a quick question: is there a package/routine to perform Box's M (like proc discrim in SAS) or some other test for whether two multivariate samples (presumed multivariate normal) have the same v-c matrix? I've looked, but can't find it. If not, I can certainly code it up myself (and perhaps submit it for inclusion in the mvtnormtest package), but I wanted to check if it

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 =

Dear List I am looking for a script that will calculate the Box M test to test the homogeneity of the variance/covariance matrix between two matrices. If anyone could send me the script I would appreciate it. I am aware of the scepticism about this test, where due to extreme sensitivity a p value of 0.01 is recommended. Despite this however Box's M test is the established

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.

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... // FAILS with org.rosuda.REngine.Rserve.RserveException: eval

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

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

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

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)

I searched the archives already and couldn't find an answer to this. I'm running an automated process via a cron job on a SUSE Linux Enterprise Server 9 box. The cron runs a Perl script, which uses the SmbClientParser module. The Perl script grabs files from clients running Windows 2000. The files on the client computers are created by in-house MFC applications on those computers.

Greeting, I''m attempting to solve a mystery we had with a puppet module we couldn''t get to auto load. The module named / folder was called "nfs" We notice when we ran ''puppetmasterd --no-daemonize --verbose'' that when the client connected that our ''nfs'' module was not being auto loaded. We reviewed and triple checked our syntax.

Hi all, I have looked around for help on creating GUIs for R, but haven't found anything. I would be interested in any advice or webpages that have information on the best language, tutorials etc. for creating simple GUIs. Mainly I want to do this as a heuristic exercise. Thanks for any help. Wade Wall [[alternative HTML version deleted]]
