morphospace_positions: Calculates nice positions on a plane for drawing shapes

In Momocs: Morphometrics using R

Calculates nice positions on a plane for drawing shapes

Description

Calculates nice positions on a plane for drawing shapes

Usage

morphospace_positions(
  xy,
  pos.shp = c("range", "full", "circle", "xy", "range_axes", "full_axes")[1],
  nb.shp = 12,
  nr.shp = 6,
  nc.shp = 5,
  circle.r.shp
)

Arguments

xy	a matrix of points typically from a PCA or other multivariate method on which morphospace can be calculated
pos.shp	how shapes should be positionned: range of xy, full extent of the plane, circle as a rosewind, on xy values provided, range_axes on the range of xy but on the axes, full_axes same thing but on (0.85) range of the axes. You can also directly pass a matrix (or a data.frame) with columns named ("x", "y").
nb.shp	the total number of shapes
nr.shp	the number of rows to position shapes
nc.shp	the number of cols to position shapes
circle.r.shp	if circle, its radius

Details

See plot.PCA for self-speaking examples

Value

a data.frame of positions
