plotDiversityTest - Plot the results of diversity testing

Description

plotDiversityTest plots summary data for a DiversityCurve object with mean and a line range indicating plus/minus one standard deviation.

Usage

plotDiversityTest(data, q, colors = NULL, main_title = "Diversity",
legend_title = "Group", log_d = FALSE, annotate = c("none",
"depth"), silent = FALSE, ...)

Arguments

data
DiversityCurve object returned by alphaDiversity.
q
diversity order to plot the test for.
colors
named character vector whose names are values in the group column of the data slot of data, and whose values are colors to assign to those group names.
main_title
string specifying the plot title.
legend_title
string specifying the legend title.
log_d
if TRUE then plot the diversity scores D on a log scale; if FALSE plot on a linear scale.
annotate
string defining whether to added values to the group labels of the legend. When "none" (default) is specified no annotations are added. Specifying ("depth") adds sequence counts to the labels.
silent
if TRUE do not draw the plot and just return the ggplot2 object; if FALSE draw the plot.
additional arguments to pass to ggplot2::theme.

Value

A ggplot object defining the plot.

Examples

# Calculate diversity
div <- alphaDiversity(ExampleDb, group="SAMPLE", min_q=0, max_q=2, step_q=1, nboot=100)

[1] 0 1 2


# Plot results at q=0 (equivalent to species richness)
plotDiversityTest(div, 0, legend_title="Sample")

4


# Plot results at q=2 (equivalent to Simpson's index)
plotDiversityTest(div, q=2, legend_title="Sample")
