[R] TWS and R

[abcd1234]

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)

 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.
