Rstudio crashes loading ORE 1.3 packages

Question

Hi,
Happy New Year, All There!!
Recently I am testing a newly released ORE 1.3 packages on Exadata X3-2 QR machine.
Under Linux shell there's no problem to run it. Looks very good..
But, when I try loading ORE packages under RStudio, the session crashes showing the following error:
======================================================
The previous R session was abnormally terminated
due to an unexpected crash.
You may have lost workspace data as a result of
this crash.
======================================================
The error message pops up just after executing the following script:
======================================================
library(ORE)
Loading required package: OREbase
Attaching package: ‘OREbase’
The following object(s) are masked from ‘package:base’:
cbind, data.frame, eval, interaction, order, paste, pmax, pmin,
rbind, table
Loading required package: OREstats
Loading required package: MASS
Loading required package: OREgraphics
Loading required package: OREeda
Loading required package: OREdm
Loading required package: lattice
Loading required package: OREpredict
Loading required package: ORExml
ore.connect(user = 'rquser',
+ password = 'rquser',
+ host = '10.xxx.xxx.xxx',
+ service_name = 'DW',
+ type = 'ORACLE',
+ all = TRUE)
Loading required package: ROracle
Loading required package: DBI
======================================================
Anybody has same problem and how to divert?
Thanks all in advance.

Hi.
May be, The R Session Error was "The previous R session was abnormally terminated due to an unexpected crash ...".
I could not test R studio on Exadata... but I just hope this tips help you.
My Installation environments are as followings.  (--> Please refer to Oracle R Enterprise Installation guide.)
- Oracle Enterprise Linux 6.4 or CentOS 6.3
- ORE (Oracle R Enterprise) 1.3.1 for Linux x86_64
- Oracle R Distrubution (R 2.15.1)
- Oracle Database 11g (11.2.0.3.0) or 11.2.0.1 and Bug 11678127 PSU --> Please refer to Oracle R Enterprise Installation guide and must apply the proper
  Oracle database patches for ORE
- RStudio version : rstudio-server-0.97.551-i686.rpm (from RStudio)
* Note :  Document --> Oracle R Enterprise Installation and Administration Guide Release 1.3 for Windows, Linux, Solaris, and AIX E36763-11
I got the same error, but I solved the problem as followings.
1) http://your_server_ip:8787
2) login as oracle
3) Setup like this on your browser, without belows Sys.setenv, you will get the error. Of course improper Oracle database setting also show you ...
    Modify this according to your environments.
4) Please refer to the following logs on Chrome browser

4. you can also test R studio like this.
   4.1) select R menu -> Tools --> shells ....
   4.2) at prompt, $ . ./bash_profile    <-- without this, you also get the crash messages.
   4.3) run R
   4.4) > library(ORE)
          > ore.connect(user="rquser",sid="dwdb", host="dwdb.localdomain", password="xxxx", port=1521, all=TRUE)
