DATA MINING
Desktop Survival Guide by Graham Williams |
|||||
We use the R language to illustrate concepts and modelling in data
mining. R is both a programming language and an interpreter. When
we illustrate interactive sessions with R we will generally show
the R prompt, which by default is ``>
''. This allows the
output from R to more easily be distinguished. However, we
generally do not include the continuation prompt (a ``+
'')
which appears when a single command extends over multiple lines, as
this makes it more difficult to cut-and-paste from the examples in the
electronic version of the book.
In providing example output from commands, at times we will truncate the listing and indicate missing components with [...]. While most examples will illustrate the output exactly as it appears in R there will be times where the format will be modified slightly to fit with publication limitations. This might involve silently removing or adding blank lines.
