Hi all, The TWS on my system is unable to connect to my R session. Here is the error that I'm getting: /> tws<-twsConnect() Error in socketConnection(host = host, port = port, open = "ab", blocking blocking) : cannot open the connection In addition: Warning message: In socketConnection(host = host, port = port, open = "ab", blocking blocking) : localhost:7496 cannot be opened/ Here is the session info for the R session: / R version 2.15.1 (2012-06-22) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_IN.UTF-8LC_NUMERIC=C [3] LC_TIME=en_IN.UTF-8LC_COLLATE=en_IN.UTF-8 [5] LC_MONETARY=en_IN.UTF-8LC_MESSAGES=en_IN.UTF-8 [7] LC_PAPER=CLC_NAME=C [9] LC_ADDRESS=CLC_TELEPHONE=C [11] LC_MEASUREMENT=en_IN.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] statsgraphicsgrDevices utilsdatasets [6] methodsbase other attached packages: [1] IBrokers_0.9-10 xts_0.8-6zoo_1.7-8 loaded via a namespace (and not attached): [1] grid_2.15.1lattice_0.20-0 tools_2.15.1/ I have checked the "Enable Activex and Socket clients" but it hasn't helped. Since I'm running on an Ubuntu machine, I even tried changing the parameter blocking in the command twsConnect() to 1. blocking = FALSE 2. According to the one mentioned here http://code.google.com/p/ibrokers/source/detail?r=84&path=/trunk/R/twsConnect.R but nothing has helped. I have also added 127.0.0.1 to the "Trusted IP" option. Please let me know what I should do. Thanks. -- View this message in context: http://r.789695.n4.nabble.com/TWS-and-R-tp4649699.html Sent from the R help mailing list archive at Nabble.com.
