RLink Java(TM) platform has stopped working

Short Answer

R cannot handle expressions that are nested very deeply. You will have to find a way to simplify your expressions.

Long Answer

I can reproduce the crash on V9 under Windows 7 64-bit with a simpler setup. Start with these definitions:

Needs["RLink`"]
InstallR[];

expr[depth_] := "function(x){"~~Nest["1+("~~#~~")"&, "x", depth]~~"}"

This will work:

REvaluate[expr[48]]

But this will not:

(* WARNING: this causes JLink/Java to crash!! *)
REvaluate[expr[49]]

And neither will this (after restarting JLink/RLink):

(* WARNING: this causes JLink/Java to crash!! *)
com`wolfram`links`rlink`RLinkInit`getRExecutor[]@eval[expr[50]]

If I evaluate the following expression (expr[50]) directly in Rgui, I get a runtime exception:

function(x){
1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(
1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(
1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(1+(
1+(1+(1+(1+(1+(x)))))))))))))))))))))))))))))
)))))))))))))))))))))
}

# Error: contextstack overflow at line 1

My guess is that this is not a bug in RLink directly -- I suspect that the JRI native library has a very nasty problem trying to handle such error conditions.

Ok,just reporting that an easy way around this problem is using ExpandAll command in mathematica,so you get rid of nested parentheses
