plotpersp_control: Control Parameters for plotpersp.cgam

Description

Constructs a list of control parameters to customize the appearance of perspective plots created by plotpersp.cgam.

Usage

plotpersp_control(surface = "mu", x1nm = NULL, x2nm = NULL, categ = NULL,
  col = NULL, random = FALSE, ngrid = 12, xlim = NULL, ylim = NULL, zlim = NULL,
  xlab = NULL, ylab = NULL, zlab = NULL, th = NULL, ltheta = NULL, 
  main = NULL, sub = NULL, ticktype = "simple")

Value

A named list of control settings for use with plotpersp.

Arguments

surface: Character string indicating the surface type to plot. Options are "mu" for fitted means or "eta" for systematic component.
x1nm: Optional character strings specifying names of the predictors for the x axis.
x2nm: Optional character strings specifying names of the predictors for the y axis.
categ: Optional character string naming a categorical covariate in the cgam fit to stratify surfaces. Default is NULL.
col: Colors used for the surface(s). If NULL, defaults are applied automatically depending on the number of surfaces.
random: Logical; if TRUE, colors are randomized for multiple surfaces. Default is FALSE.
ngrid: Integer; number of grid points along each axis. Default is 12.
xlim, ylim, zlim: Optional numeric vectors of length 2 specifying limits for the x, y, and z axes.
xlab, ylab, zlab: Axis labels for x, y, and z axes. Default is based on the predictor names and surface type.
th: Angle defining the azimuthal direction for viewing the plot (theta).
ltheta: Angle defining the direction of lighting (light theta).
main: Main title of the plot.
sub: Subtitle of the plot.
ticktype: Character string indicating type of tick marks: "simple" (default) or "detailed".

Examples

Run this code

ctrl <- plotpersp_control(col = "topo", ngrid = 20, th = 45)
# Then used inside plotpersp:
# plotpersp(fit, control = ctrl)
