Hi Duncan Thanks for the reply. Unfortunately, the Excel process still persists indefinitely even after removing the handle E and issuing the gc() command -- even after closing R, too. For the moment, I have found a way round this by issuing a shell command to "kill" the process.

There may well be an extra reference in R to the Excel application that keeps it hanging around. Can you try the following and let me know if you still see the same problem: 1) make certain there are not Excel processes running 2) Create an Excel from R and quit E <- COMCreate("Excel.Application") E[["Visible"]] <- TRUE E$Quit() 3) rm(E) 4) gc() 5) wait a 30 seconds or so 6) check if the Excel instance is still running. Thanks. D.
