Plot One-Way ANOVA Minimum Sample Size Under the Falconer Model

Source: R/plot_falconer.R

Sweeps one model or design parameter and repeatedly calls qtl_anova_mssn().

plot_qtl_anova_mssn(
  x_var,
  x_values,
  title = NULL,
  x_label = NULL,
  y_label = NULL,
  return_data = FALSE,
  ...
)

Arguments

x_var

Parameter to vary. One of "power", "alpha", "qtl_var", "tau", or "pd".

x_values

Numeric vector of at least two finite x-axis values.

title

Optional plot-title override.

x_label

Optional x-axis-label override.

y_label

Optional y-axis-label override.

return_data

Logical. If TRUE, returns plotting data rather than a ggplot object.

...

Fixed arguments passed to qtl_anova_mssn().

Value

A ggplot object, or a data frame with the swept parameter and required_N if return_data = TRUE.

Details

The x-axis is x_values for the selected x_var; the y-axis is the minimum total sample size returned by qtl_anova_mssn(). Target power and other arguments in ... remain fixed unless selected as x_var.

Examples

plot_qtl_anova_mssn(
  x_var = "qtl_var", x_values = c(0.015, 0.025, 0.05),
  power = 0.8, alpha = 0.0001, tau = 0.5, pd = 0.15
)
