Dear R Community,
 
I am trying to run a command line in R that will open an external program, have it import a specific input file, run the program, then close the program. The command line that I got from the developer of the model to do this looks like what you see below:
 
c:\programx.exe -import 'inputx.inp' -run -quit
 
I have been trying to use shell() or shell.exec() to run this in R.  I can get R to open the program but I have not been able to do the rest of the steps. 
 
I have been able to open the model using :
 
>shell('"C:\\programx.exe"')
 
or
 
>shell.exec("C:\\programx.exe")
 
To do the rest I have been trying variations of the following:
 
>shell('"C:\\programx.exe"' -import '"C:\\inputx.inp"' -run –quit)
 
but I am not getting anywhere.
 
Can you provide any insight as to how to do the rest?
 
Thank you,
 
Galen
