match.datasets: match.datasets

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

Description

Matches two arrays by their dimnames

Usage

match.datasets(data.1, data.2)

Arguments

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

Details

Takes the two translated arrays and joined them by dimnames. Unmatched datasets (specimens missing in data.1 or data.2) are deleted.

Value

This function returns a list with the two translated arrays of dimensions (p, 3, n), in which dimnames associated with each specimen (n) are in the same order.

Examples

# We need to match the dimnames of the translated datasets, but we have two
# extra specimens in data.1_t

length(dimnames(data.1_t)[[3]]) # n=12
length(dimnames(data.2_t)[[3]])  # n=10
matched <- match.datasets(data.1_t, data.2_t)

# When we matched the arrays, only matrices from specimens present in both
# datasets will be kept

length(dimnames(matched$matched1)[[3]]) # n=10

length(dimnames(matched$matched2)[[3]])  # n=10
