cd ~ gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys E084DAB9 gpg -a --export E084DAB9 | sudo apt-key add - apt-get upgrade apt-get install r-base

ROracle is much faster compare with RODBC or RJDBC in performance, You can found new version of ROracle or DBI package in CRAN, it is also required you properly install the Oracle Instant Client.

manual install the ROracle

wget http://cran.r-project.org/src/contrib/DBI_0.2-7.tar.gz R CMD INSTALL DBI_0.2-7.tar.gz wget http://cran.r-project.org/src/contrib/ROracle_1.1-11.tar.gz R CMD INSTALL --configure-args='--with-oci-inc=/opt/oracle/instantclient_11_2/sdk/include --with-oci-lib=/opt/oracle/instantclient_11_2' ROracle_1.1-11.tar.gz

RStudio Server

Install RStudio Server

apt-get install gdebi-core apt-get install libapparmor1 # Required only for Ubuntu, not Debian wget http://download2.rstudio.org/rstudio-server-0.97.551-i386.deb gdebi rstudio-server-0.97.551-i386.deb rstudio-server verify-installation

echo 'rsession-memory-limit-mb=1000' > /etc/rstudio/rserver.conf echo 'rsession-stack-limit-mb=4' >> /etc/rstudio/rserver.conf echo 'rsession-process-limit=20' >> /etc/rstudio/rserver.conf # Only pass below if you will using proxy mode echo 'www-address=127.0.0.1' >> /etc/rstudio/rserver.conf groupadd rstudio

This section is optional, assured already install nginx in server.

# do not forgot link to /opt/nginx/conf/vhosts server { listen 80; server_name cvprstudio; location / { proxy_pass http://localhost:8787; proxy_redirect http://localhost:8787/ $scheme://$host/; } }

ln -s /usr/lib/rstudio-server/extras/init.d/debian/rstudio-server /etc/init.d/rstudio-server vi /etc/init.d/rstudio-server

vi

# append below line to /usr/lib/rstudio-server/extras/init.d/debian/rstudio-server SCRIPTNAME ORACLE_BASE=/opt/oracle ORACLE_HOME=/opt/oracle/instantclient_11_2 TNS_ADMIN=/opt/oracle/network/admin NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Now you can restart rstudio-server via standard init.d service way

/etc/init.d/rstudio-server restart

adduser --ingroup rstudio cindy passwd cindy # setting password

Usually it is more good to upgrade the r-base in system wide packages instead of per user.

after run R in root console

update.packages() # select mirror to check
