Conditional density plot
This is a type of conditional plot where the distribution of a categorical variable is shown to change over the values of a continuous variables. In the example, the distribution of the variable indicating the distribution of the treatment outcome (for an arthritis blind trial conducted in 1988) is plotted against age.
This is a lattice graph, that allows the presentation histograms for more than one variable.
A visualisation to display a variable distribution conditional on the distribution of at least a second variable. In the example, the number of breaks is displayed conditional on the type of wool and the level of tension.
A conditioning plot with splines added. It allows the visualisation of a variable distribution conditional on the values of the relevant groups of interest.
Lattice confidence intervals
A simple graph that allows the presentation means and confidence intervals of several inter-related variables in an experiment.
This is a lattice plot that displays scatter plots for three variables grouped in three clusters, in the example. Useful for a quick visualisation of the contingencies of the data set.
