slouch (version 2.1.5)

plot.slouch: Plot Grid Search

Description

Graphical plot of parameter space traversed by the grid search.

Usage

# S3 method for slouch
plot(x, theta = 30, phi = 30, expand = 0.5, shade = 0.75, ...)

Arguments

x

An object of class 'slouch'

theta, phi

angles defining the viewing direction. theta gives the azimuthal direction and phi the colatitude.

expand

a expansion factor applied to the z coordinates. Often used with 0 < expand < 1 to shrink the plotting box in the z direction.

shade

the shade at a surface facet is computed as ((1+d)/2)^shade, where d is the dot product of a unit vector normal to the facet and a unit vector in the direction of a light source. Values of shade close to one yield shading similar to a point light source model and values close to zero produce no shading. Values in the range 0.5 to 0.75 provide an approximation to daylight illumination.

Examples

data(artiodactyla)
data(neocortex)

neocortex <- neocortex[match(artiodactyla$tip.label, neocortex$species), ]

m0 <- slouch.fit(phy = artiodactyla,
                 hl_values = seq(0.001, 50, length.out = 15),
                 vy_values = seq(0.001, 3, length.out = 15),
                 species = neocortex$species,
                 response = neocortex$body_mass_g_log_mean,
                 mv.response = neocortex$body_mass_g_log_varmean,
                 fixed.fact = neocortex$diet)
