[R] rcom close Excel problem

Thank you, getobject is a roundabout, but solves the issue. BTW I 
discovered that

 system("taskkill /f /im Excel.exe") # kills the process just fine.

The second problem is not due to the backslash vs slash, you can try 
and see that using the forward slash works fine from ESS. The q. is how 
to submit a second argument to "Close"?
Submitting a second argument to Open works fine as shown by the "0" 
below, but neither "1" nor "-1" worked for Close. Very strange.

I know it won't answer your question exactly, but using comGetObject  
instead of comCreateObject won't create new Excel instances, so at  
least you won't have more than one processes running, so this might  
solve some of your problems.

As for your second problem, I would venture to guess you need your  
paths with double backslashes instead of slashes. The following just  
worked over here:

  wb<-comInvoke(comGetProperty(obj,"Workbooks"),"Open", "C:\ 
\Documents and Settings\\Haris\\Desktop\\test1.xlsx")
