## 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.

export.eps | Exports a graph to an EPS file. | |

norm.curve | plot a normal or a t-curve with both x and z axes. | |

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

grid.yaxis.hh | make x- and y-axis labels | |

col.hh | Initializing Trellis Displays | |

as.multicomp | Support functions in R for MMC (mean--mean multiple comparisons) plots. | |

positioned-class | Class "positioned", extends "ordered" to specify the position for graphing the levels of a factor. | |

multicomp.reverse | Force all comparisons in a "multicomp" object to have the same sign. | |

partial.corr | partial correlations | |

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

xysplom | scatterplot matrix with potentially different sets of variables on the rows and columns. | |

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

plot.hov | Homogeneity of Variance Plot | |

objip | loop through all attached directories looking for pattern | |

mmc.mean | MMC (mean--mean multiple comparisons) plots from the sufficient statistics for a one-way design. | |

ci.plot | Plot confidence and prediction intervals for simple linear regression | |

strip.xysplom | strip function that is able to place the correlation or regression coefficient into the strip label. | |

resid.squares | plot squared residuals in inches to match the y-dimension | |

strip.background0 | Turn off the coloring in the trellis strip labels. Color 0 is the background color. | |

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

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

aov.sufficient | Analysis of variance from sufficient statistics for groups. | |

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

anova.mean | ANOVA table from the group sample sizes, means, and standard deviations. | |

plot.multicomp | Multiple comparisons plot that gives independent user control over the appearance of the significant and not significant comparisons. | |
