[R] R.matlab package help

[michael]

I updated R and still have the problem.
When I set
remote = true, it reports:

??? Undefined variable "java" or class "java.io.InputStreamByteWrapper".

Error in ==> MatlabServer at 262
    reader = java.io.InputStreamByteWrapper(4096);

and I changed remote = false, same problem pops up:

??? Error: A MATLAB string constant is not terminated properly.

Error in ==> MatlabServer at 197
      eval(expr);


Thanks,

Michael
