archmap: Archetypal maps

In archetypes: Archetypal Analysis

Description

Two-dimensional projection of the observations based on the alpha coefficients into a space spanned by the (projected) archetypes.

Usage

archmap(object, projection = simplex_projection, projection_args = list(),
  rotate = 0, cex = 1.5, col = 1, pch = 1, xlab = "", ylab = "",
  axes = FALSE, asp = TRUE, ...)

Arguments

object	An archetypes object
projection	Projection function; see archmap_projections
projection_args	Arguments passed to the projection function; see archmap_projections
rotate	Rotation angle to rotate the projection
cex	Character expansion of archetypes
col	Color of observations
pch	Point character of observations
xlab	A label for the x-axis
ylab	A label for the y-axis
axes	Logical value to draw axes or not
asp	The y/x aspect ratio
...	Arguments passed to the underlying plot function

Value

Invisible matrix with the projected archetypes

Examples

## Not run: 
  data("skel", package = "archetypes")
  skel2 <- subset(skel, select = -Gender)

  set.seed(1981)
  a <- archetypes(skel2, k = 5)

  ## Simplex projection:
  archmap(a, col = skel$Gender)

  ## Simplex projection with archetypes arranged according to their
  ## distances:
  archmap(a, col = skel$Gender,
          projection = tspsimplex_projection)
  archmap(a, col = skel$Gender,
          projection = tspsimplex_projection,
          projection_args = list(equidist = TRUE))

  ## MDS projection:
  archmap(a, col = skel$Gender,
          projection = atypes_projection)

## End(Not run)
