Re: [R] system() command in R
Thank you all for the suggestions. I've been trying different things to make this work. Mike I did try what you suggested . It would work normally But i guess here the problem is my local server itself. It by default takes time to start and nothing I do is helping . So I came up with the idea to communicate with the server through R-java connection. I am halfway through that , I hope it works:) Thank you all for the response.

I just got done with some java code to do something similar and you can expect in any implementation these things will be system dependent. It often helps to have simple test cases to isolate the problem. Here I made a tst script called foo that takes a minute or so to exevute and generates some output. If I type system(./foo,wait=F) the prompt comes back right away but stdout seems to still go to my console and maybe stdin is not redicrected either and it could eat your input ( no idea, but this is probably not what you want). I did try this that could fix your problem, on debian anyway it seems to work, system(nohup ./foo ) you can man nohup for details.

Re: [R] system() command in R
Hi, The further steps do not get executed because the server keeps waiting. and they are in the same function as the start server. if server started manually then they run normally from the R environment. Is that what you wanted to know? I hope I answered it .

[R] system() command in R
Hi all, I have a local server insalled on my system and have to start that from within my R function. here is how I start it: cmd-sh start-server.sh system(cmd, wait=FALSE) My function has to start the server and proceed with further steps.
