## Statistical Analysis and Data Display: Heiberger and Holland

Support software for Statistical Analysis and Data
Display (Springer, ISBN 0-387-40270-5). This contemporary
presentation of statistical methods features extensive use of
graphical displays for exploring data and for displaying the
analysis. The authors demonstrate how to analyze data---showing
code, graphics, and accompanying computer listings---for all the
methods they cover. They emphasize how to construct and
interpret graphs, discuss principles of graphical design, and
show how accompanying traditional tabular results are used to
confirm the visual impressions derived directly from the
graphs. Many of the graphical formats are novel and appear
here for the first time in print. All chapters have exercises.

ancova-class | Class "ancova" Analysis of Covariance | |

plot.hov | Homogeneity of Variance Plot | |

bwplot.formula | Replacement for bwplot.formula and compute.packet in R to allow them to work with the new "positioned" class. | |

panel.bwplot.intermediate.hh | Panel functions for bwplot. | |

residual.plots | Residual plots for a linear model. | |

orthog.complete | Construct an orthogonal matrix which is an arbitrary completion of the column space of the input set of columns. | |

panel.pairs.hh | Function based on S-Plus panel.pairs to add the subpanel.scales and panel.cex arguments. | |

panel.ci.plot | Default Panel Function for ci.plot | |

ladder | Draw a "ladder of powers" plot, plotting each of several powers of y against the same powers of x. | |

mmc | MMC (mean--mean multiple comparisons) plots. | |

mcalinfct | MCA multiple comparisons analysis (pairwise) | |

X.residuals | Residuals from the regression of each column of a data.frame against all the other columns. | |

multicomp.order | Update a multicomp object by ordering its contrasts. | |

t.trellis | Interchange the x- and y-axes for an S-Plus trellis object. Identity function for an R lattice object. | |
