Learn some basic debugging for R. There are several functions (debug, browser, ...) that can help. Put the following in your Startup script:
options(error=utils::recover) or at least execute it manually. This will give you the trace of the stack when the error happens and may help you identify the statement that is causing the problem. This may allow you to examine the various objects you have at that point in time. So there are ways that you can find out what the problem is, but you will have to invest some time in learning how to debug your code. There is also the 'debug' package which provides a nice way of tracing execution in a function, but I think first follow the hints above to trap when the error occurs so you can trace down what is causing it.
