/ Posters - An introduction to R
a statistical package to the biologist's fingertips.
An introduction to R (Splus) with applications
to microarray analysis.
Speaker: Natalie Roberts
Many of you will have heard of the
statistical package Splus. There is
also a similar freeware package
called "R". These programs are very
useful for a range of analyses
because they are flexible and easily
programed to your specific needs.
But these programs need not be limited
to use by statisticians.
I will provide tutorial-style handouts
of introductory material to be
covered in the first part of the
talk. In addition, I will illustrate how
to use R for the analysis of microarray
data. Many of you will be
considering the use of microarray
technology in the future. Once your
image has been analysed and you
are given data on each spot, how will you
analyse it? I will provide
examples and advice on appropriate options
available through R.
Although complicated analyses will
need guidance from a statistician, many
analyses are relatively simple
if you have a tool such as Splus or R at
your fingertips. The use of such
programs may also promote a greater
understanding of the analyses you
No prior knowledge of R or Splus
is assumed and only simple statistical
ideas will be covered.
