Conflict with xlsx package and choose.files


I always use these lines at the top:

options(java.parameters="-Xmx4000m")options(java.home="C:/Program Files/Java/jre7/")

See if maybe that helps.


Try clearing out your Temp files from

Control Panel > Programs > Java

See if it works.


I recently had this issue with an installation of R on a new machine. Make sure you are using the correct version of Java (32-bit vs 64-bit) to match your version of R. Note that the 64-bit version of Java is not found on their main download page but on their "manual" d/l page here.
