view_manip_space: Plot 2D projection frame and return the axes table.

In spinifex: Manual Tours, Manual Control of Dynamic Projections of Numeric Multivariate Data

Plot 2D projection frame and return the axes table.

Description

Uses base graphics to plot the circle with axes representing the projection frame. Returns the corresponding table. Only works for 2d manual tours.

Usage

view_manip_space(
  basis,
  manip_var,
  tilt = 0.1 * pi,
  basis_label = abbreviate(row.names(basis), 3),
  manip_col = "blue",
  manip_sp_col = "red",
  line_size = 0.6,
  text_size = 4
)

Arguments

basis	A (p, d) orthonormal numeric matrix. The linear combination the original variables contribute to projection space. Required, no default.
manip_var	Number of the column/dimension to rotate.
tilt	angle in radians to rotate the projection plane. Defaults to .1 * pi.
basis_label	Optional, character vector of p length, add name to the axes in the frame, defaults to 3 letter abbriviation of the orginal variable names.
manip_col	String of the color to highlight the manip_var.
manip_sp_col	Color to illustrate the z direction, orthogonal to the projection plane.
line_size	The size of the lines of the unit circle and variable contributions of the basis. Defaults to 1.
text_size	The size of the text labels of the variable contributions of the basis. Defaults to 5.

Value

ggplot object of the basis.

Examples

library(spinifex)

dat_std <- scale_sd(wine[, 2:6])
bas     <- basis_pca(dat_std)
mv      <- manip_var_of(bas)

view_manip_space(basis = bas, manip_var = mv)

view_manip_space(basis = bas, manip_var = mv,
                 tilt = 2/12 * pi, basis_label = paste0("MyNm", 1:ncol(dat_std)),
                 manip_col = "purple", manip_sp_col = "orange")
