Overview
1
We are starting with 54 web pages.
2
We want to end up with some plots
(based on various subsets of the numbers and text in those
web pages).
We will have three main aims along the way ...
1
Learn basic programming tools: introduce or review R
functions for working with data.
2
Learn how to program: demonstrate how the basic tools are
combined together to perform larger tasks.
3
Learn how to manage R code: techniques for organising and
reorganising larger amounts of R code.
More than solving the task itself, we will be interested in the tools
and techniques that we use to solve the task.
