In spathial: Evolutionary Analysis

Description

Get the coordinates of the starting and ending points

Usage

spathialBoundaryIds(X, X_labels = NULL, mode = 1, from = NULL, to = NULL)

Arguments

X	data points
X_labels	labels of the data points
mode	strategy for boundary selection 1 - selected by the user 2 - centroids 3 - insert the row name of the starting and ending points
from	starting class or row name of the starting point
to	ending class or row name of the ending point

Value

A list of objects

• boundary ids: the indexes of the boundaries

• X: the new data matrix with the boundary

• X_labels: the new labels of the data matrix with the boundary labels

Examples

# Load data matrix X
load(system.file('extdata','X.rda',package='spathial',mustWork=TRUE))
# Load description vector X_labels
load(system.file('extdata','X_labels.rda',package='spathial',mustWork=TRUE))
# Run spathialBoundary
boundaryRes <- spathialBoundaryIds(X, X_labels, mode=2, from=3, to=6)
