 
Summary: An Introduction to R
Introduction
R is a statistical computing package which will run under most commonly used operating systems. It will be used
in all statistics modules taught by the School of Mathematics at the Univerity of Leeds and is installed on the
networked PCs around the campus. If you have your own PC, you can download 1
your own copy of R from the
comprehensive R network website: www.stats.bris.ac.uk/R/. The file you need to download is about 33 megabytes.
Some guidance on the installation procedure is given at the end of this document.
A much longer Introduction to R is available from www.stats.bris.ac.uk/R/doc/manuals/Rintro.pdf (this page is
also available from within R) and other introductory documents are on the School of Mathematics' page:
www.maths.leeds.ac.uk/school/students/computing.html. Many of these documents are also available in the Help
menu. This guide is intended for those who have never used R. As a minimum, you should read (and work through)
to the end of the next section.
An Introductory Session
This section describes a session on the University ISS network.
After logging in, click on Start (bottom left corner of your screen), then All Programs, then choose Statistics,
and finally R [version 2.13]. This will open a large window called "R Gui" (GUI stands for Graphical User Interface).
This large window can contain one or more subwindows, in particular:
· An R Console window (which should always be present). This is where you can type your commands.
· A graphics window will appear automatically when any plotting commands are issued.
