[R] shell and shell.exec on Windows

[Erich Neuwirth]

I have an Excel workbook "MyWorkbook.xls" containing an Auto_Open macro
which I want to be run from R.

shell.exec("MyWorkbook.xls")
does that.

shell("start MyWorkbook.xls")
also runs it.

In both cases, the Excel window is visible on screen when Excel is started.
Is there a way of opening the sheet with a hidden Excel window?
start has some parameters (e.g. /MIN), which should allow this, but
shell("start /MIN MyWorkbook.xls")
also starts Excel visibly.
