Getting OWA to work with Ubuntu

My univeristy is currently in the last stages of relying on exchange 2003, only supporting Microsoft software. So after suffering painfully trying to get evolution working, i gave up went and got a java based application to get my email via Thunderbird.

Setup instructions
Download latest deb package of Davmail here and install
Download Thunderbird
sudo apt-get install Thunderbird

The settings for Davmail and Thunderbird are best described here. Using the other tutorials on this site it is also possible to setup contacts and your calender.

The owa for Sydney uni is https://www.owa.usyd.edu.au/exchange/.
It is also important to set the proxy settings in the proxy tab, if on campus.

Installing R, Emacs and ESS in Ubuntu

When using R under Ubuntu, You need to tell your Ubuntu system where to obtain R from.
This is easly done by adding the url location to the repository list. I tend to do this using the
application gedit (can be found under
Application > Accessories > Text Editor). The sudo gives the user
admin rights to edit the file. This line is typed into a terminal window (found under
Application > Accessories > Terminal).

sudo gedit /etc/apt/sources.list

I want to add the Melbourne repo so I added

deb http://cran.ms.unimelb.edu.au/bin/linux/ubuntu jaunty/

to the end of the file.

Save and close gedit.

Now update the repo


sudo apt-get update

To update the key so the automatically update R.

gpg --export --armor E2A11821 | sudo apt-key add -


to install R run

sudo apt-get install r-base r-base-dev r-recommended

To run R open a terminal window, and type

R


website: http://www.r-project.org/

Now install Emacs - The best R editor I have found, so far.

sudo apt-get install emacs

website: http://www.gnu.org/software/emacs/

Now emacs is installed you need to install ESS (Emacs speaks statistics)

sudo apt-get install ess


website:
http://ess.r-project.org/



On a side (Briefly)

to install packages in R use the command with R

install.packages("package")
