[R] R: Securities earning covariance

[R. Michael Weylandt]

I'm somewhat confused:

i) What does this have to do with your subject line?

ii) There does not exist -- to my knowledge -- an implementation of R
which runs on the JVM.

iii) Have you simply looked into R's native parallel computing
options? That seems to be (maybe?) what you are trying to do.

Incidentally, thanks to the in-memory model, it is possible to spawn
multiple R processes which use the same package libraries [the package
is the thing in the library, which is tied to the filesystem] on the
same machine (I'm thinking real, but this shouldn't be a problem with
a reasonable VM setup either)
