coo_template: 'Templates' shapes

In Momocs: Morphometrics using R

'Templates' shapes

Description

coo_template returns shape centered on the origin and inscribed in a size-side square. coo_template_relatively does the same but the biggest shape (as prod(coo_diffrange)) will be of size=size and consequently not defined on single shapes.

Usage

coo_template(coo, size)

## Default S3 method:
coo_template(coo, size = 1)

## S3 method for class 'list'
coo_template(coo, size = 1)

## S3 method for class 'Coo'
coo_template(coo, size = 1)

coo_template_relatively(coo, size = 1)

## S3 method for class 'list'
coo_template_relatively(coo, size = 1)

## S3 method for class 'Coo'
coo_template_relatively(coo, size = 1)

Arguments

coo	A list or a matrix of coordinates.
size	numeric. Indicates the length of the side 'inscribing' the shape.

Details

See coo_listpanel for an illustration of this function. The morphospaces functions also take profit of this function. May be useful to develop other graphical functions.

Value

Returns a matrix of (x; y)coordinates.
