This is not a direct answer to your question, but if all you want to do is
integrate a function numerically, you don't need to be doing it through R.
You should be able to find codes that you can use directly, such as quadpack
or even GSL.  You may want to search on GAMS (Guide to Available
Mathematical Software, http://gams.nist.gov/).
