[Yuan, Rebecca]

Hello Jim,

I already use “.xls” for the loading, but still have the memory issue….

Thanks,

Rebecca

On the off-chance, are you using XLConnect or xlsx packages that are using Java to access the spreadsheets?  If it is XLConnect, are you access the '.xlsx' style workbooks?  If so, can you try using '.xls' workbooks?  This is a problem that I have had; the '.xlsx' workbooks take a lot more resources (CPU and memory) to process.

A little more information like what your sessionInfo is would help a lot in responding to your problem.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

The memory issue is in Java, not R.

You can either be more parsimonious in your use of Java memory (we have no idea what you are doing with it here, so how you do that is up to you), or you can allocate more memory to Java (you may be able to guess how to do that, or read the Java documentation on the X parameter).
