[R-SIG-Mac] Word / OS X / R

[Dennis Fisher]

R 2.13.1
OS X. 10.6.8
Colleagues,

I just encountered an interesting Word / OS X / R interaction problem.  Situation is:
	1.  I have an open RTF file
	2.  From R:
		a.  I delete the file (confirmed)
		b.  I create a new RTF file with the same name (successfully)
		c.  I attempt to open the new RTF file
Word hangs (a recursive message that it can't open the file -- it must be corrupt), presumably because the original file was open in Word, despite being deleted from the drive.  

Any ideas on how to solve this?  Is there some method (from R or from the OS) to detect which files Word has open?   If so, I could avoid creating the new file if the original one was open.
Interestingly, I presume that this would not happen in Windows because step 2a could not happen if the file were open.
