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")
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 pushi

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 codi

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),
n
ALMOST THERE
I have one small remaining problem.
Now that I can read in the CSV data, thanks again for that help, I create a
data frame from all the REXPDouble and the one REXPString object and I'm then
trying to do a boxM (Box's M) test.
The documentation says that a data frame should wor

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 i
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 (sampl
