Typographical Conventions

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.
