join.arrays: join.arrays

In ShapeRotator: Standardised Rigid Rotations of Articulated Three-Dimensional Structures

Description

Joins the two rotated arrays and returns a single array

Usage

join.arrays(data.1, data.2)

Arguments

data.1	an object of the class "array" that contains the rotated three-dimensional landmarks for structure #1 (e.g. skull)
data.2	an object of the class "array" that contains the rotated three-dimensional landmarks for structure #2 (e.g. mandible)

Details

This function join the two arrays that were rotated using double.rotation() or simple.rotation() and return a big array from joining the two smaller arrays. It is possible to translate one of the objects after the rotation, in the case of not wanting them in contact to one another, or in a slightly different location. The vector used in the translation might have to change depending on the angle used in the rotation function, in order to represent biologically-relevant positions of the two structures relative to one another.

Value

This function returns an array of the joined two arrays comprising the two rotated structures (e.g. mandible and skull).

Examples

rotation_45 = double.rotation(data.1, data.2, land.a, land.b, land.c, land.d,
land.e, land.f, land.g, land.h, 45)

rotation_45_t <- join.arrays(rotation_45$rotated1, rotation_45$rotated2)

# The datasets can also be joined after further translation
rotation_45_t <- join.arrays(rotation_45$rotated1,
translate(rotation_45$rotated2, land.e , skull_translate))
