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
