morphospace_positions {Momocs}

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
