We're using Rserve as a back-end in our application. A problem that we experienced is that the Rserve connection gets stuck when R is asking for some kind of user interaction. For example, when executing an 'install.packages' command for the first time without specifying the repos argument, R will prompt a list to specify a mirror, and does not return. To solve this, we need to set R to non-interactive (see ?interactive), but it's hard to find out how. Jeffrey Horner has been so kind to write a little piece of c code that sets the C level global variable R_Interactive (see package 'interactivity' on cran), but I was wondering if there is an easier way to start R in non interactive mode. -- View this message in context: http://r.789695.n4.nabble.com/Setting-R-Interactive-tp2322621p2322621.html Sent from the R help mailing list archive at Nabble.com.
