Static 2D perspective plot of p-value surface

Source: R/plot_p_static.R
plot_p_static.Rd

Plots the output of p_surface using base R's persp function. This produces a static 3D perspective plot with no external dependencies, making it suitable for PDF output, journal figures, and CRAN checks.

Usage

plot_p_static(
  surface,
  theta = 30,
  phi = 20,
  col = "steelblue",
  shade = TRUE,
  alpha = 0.05
)

Arguments

surface

A list returned by p_surface.

theta, phi

Viewing angles in degrees. See persp for details. Defaults: theta = 30, phi = 20.

col

Color palette for the surface. Either a single color or a vector of colors matching the number of \(d \times n\) grid cells.

shade

Logical; if TRUE (default), the surface is shaded using persp's shading.

alpha

Significance level. A horizontal plane at \(p = \alpha\) is overlaid on the surface. Default: 0.05.

Value

Invisibly returns the input surface object. Called for its side effect (a plot).

Details

Unlike plot_p_surface, which requires rgl or plotly, this function uses only base R graphics. It is ideal for inclusion in static documents such as PDF articles and printed reports.

Examples

# Compute surface
surface <- p_surface(d = seq(-2, 2, 0.1), n = seq(5, 200, 5))

# Static perspective plot
plot_p_static(surface)


# Different viewing angle
plot_p_static(surface, theta = 45, phi = 30)
