You can start diagnosing the problem by capturing the matrix that caused
eigen() to stop. You can do this in a variety of ways; here is one
trace(eigen, quote(lastEigenX <<- x))
After setting the trace, make your offending function call and after the
error the global variable 'lastEigenX' will contain the bad matrix. Take
the trace off of eigen
If all goes well then
will cause the same error and you or someone on this list can see what
is odd about that matrix (e.g., by looking at its singular values).
