R devel - Mar 2011 - passing a 2D array from Java to R

Hello, 

I have a 2D array of type double in java and I want to pass this data to R
in order to compute some statistics. Can anyone help me with this ?

The best place would be the appropriate mailing list of the package that use use
for R/Java communication. If it's rJava then stats-rosuda-devel mailing is
the list to ask.

In R matrices are vectors of the length m*n so you can either create one array
with the values in Java, assign it (let's say to A) and call matrix(A,m,n)
or you can simply pull the array as-is to R and run something like
sapply(a,.jevalArray).
