[R] rJava Out of Memory Error

[Martin Studer]

Hi Matthew,

The problem is that the underlying JVM is running with a fixed maximum heap
size. When you load a workbook in XLConnect, an in-memory representation of
that workbook is created (in Java by Apache POI). Reading and writing data
additionally requires memory due to "communication" of your data from and to
the JVM. Depending on the size of your workbooks and the data you are
dealing with you may need to increase the maximum heap size available to the
JVM. Please have a look at our FAQ at
http://www.mirai-solutions.com/site/index.cfm?id_art=69890&actMenuItemID=31456&plainerr=yes&vsprache=EN
on how to do this.

Other functions that you might be interested in are xlcMemoryReport and
xlcFreeMemroy.

Hope that helps.

Best regards,
Martin
