Uwe,
Thank you so much for the response. I tried running the command in the format
you suggested but still could not get the shell command to execute. The
following is the command that I used per your suggestion and the subsequent
error message.
shell('"C:\\programx.exe"' -import '"C:\\inputx.inp"' -run -quit)
This cannot work. Is this all expected to be the first argument of
shell()? If so, you need to quote it as a whole.
#Error that is returned from above code…..
'C:\Program' is not recognized as an internal or external command, operable
program or>batch file
Since the above command cannot work, this error message is the resukt
from another call you have not given.
Particularly the "c:\Program" points us to a problem with spaces in the
directory "Program Files" but since you have not used that in your call
from R, it must be something in C:\programx.exe or C:\inputx.inp that
causes the problem, but it is not R related - unless you have used a
completely different call.
Warning message:
In shell("\"C:\\programx.exe\" -import>\"C:\\input.inp\" -run -quit") :
>'"C:\programx.exe" -import "C:\input.inp" -run -quit' execution failed with
error code 1
These two lines are also from two different calls. I don't see the ">"
from the first line is in the second line now....
So, *please* copy and paste only code and error messages that fit to
each other!

Thinking that it may be a problem with the command line I checked with
developer of the program and he said that it should be the correct language.
Any thoughts?
Thank you again,
Galen

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)
Hm, you need to pass one string to the shell (and the underlking
system()) call:
shell('"C:\\programx.exe" -import "C:\\inputx.inp" -run –quit')
Best,
Uwe Ligges
but I am not getting anywhere.
Can you provide any insight as to how to do the rest?
Thank you,
Galen
