coords: Extract coordinates from an object

In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Extract coordinates from an object

Description

This function extracts the coordinates from an input object.

Usage

coords(x, ...)

Arguments

x	The object to extract coordinates from.
...	Additional arguments (not used in the generic function).

Value

A numeric matrix or vector containing the coordinates of x.

Examples

# Create a NeuroSpace object with 3mm voxels
space <- NeuroSpace(c(10,10,10), spacing=c(3,3,3))

# Create ROI coordinates in voxel space
coords <- matrix(c(1,1,1, 2,2,2), ncol=3, byrow=TRUE)
roi_coords <- ROICoords(coords)

# Get coordinates in voxel space
vox_coords <- coords(roi_coords)
# First coordinate is (1,1,1)

# Get coordinates
cds <- coords(roi_coords)
nrow(cds) == 2
