plot_pep: Plot the Posterior Exchangeability of a Basket Trial

Description

The posterior exchangeability of the baskets in an an MEM analysis can be visualized via an exchangeogram using this function.

Usage

plot_pep(x, ...)

Arguments

x

the exchangeability model.

...

other options passed to ggplot2 to alter the visual characteristics of the plot. See Details for more information.

Details

The `plot_pep` attempts to place the basket names to the left of the main diagonal in a way that makes it easy to read. However, for especially long basket names options are provided to ``fine tune'' the visualizations. These auxiliary options include:

• [low] The color corresponding to a low degree of exchangeability. (Default "black")

• [high] The color corresponding to a high degree of exchangeability. (Default "red")

• [mid] The color corresponding to 50% exchangeability. (Default "orange")

• [expand] The proportion to expand the viewport (Default expand = c(0.3, 0.3))

• [text_size] The text size. (Default 4)

• [legend_position] The legend position. (Default legend_position = c(0.25, 0.8)

• [draw_legend] Should the legend be drawn? (Default TRUE)

• [basket_name_hoffset] The horizontal offset of the basket names.. (Default 0)

• [basket_name_hjust] The basket name justification.. (Default 1 - right justified)

Examples

# NOT RUN {
# Create an MEM analysis of the Vemurafenib trial data.
data(vemu_wide)

mem_analysis <- mem_exact(vemu_wide$responders,
                          vemu_wide$evaluable,
                          vemu_wide$baskets)
