view_manip_spaceR Documentation

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")
