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 plot
