archmap {archetypes} R Documentation

## Archetypal maps

### 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

Other archmap: `archmap_projections`, `atypes_projection`, `simplex_projection`, `tspsimplex_projection`

### 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)
```
