coords-methods: Extract Coordinates from an IndexLookupVol Object

In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Extract Coordinates from an IndexLookupVol Object

Description

Extracts the coordinates from an IndexLookupVol object based on a given index.

Usage

## S4 method for signature 'IndexLookupVol'
coords(x, i)

## S4 method for signature 'ROIVol'
coords(x, real = FALSE)

## S4 method for signature 'ROICoords'
coords(x, real = FALSE)

## S4 method for signature 'ROICoords'
coords(x, real = FALSE)

## S4 method for signature 'AbstractSparseNeuroVec'
coords(x, i)

Arguments

x	An IndexLookupVol object to extract coordinates from
i	The index into the lookup volume
real	if TRUE, return coordinates in real world units

Value

A matrix of coordinates

Examples

space <- NeuroSpace(c(64, 64, 64), c(1, 1, 1), c(0, 0, 0))
ilv <- IndexLookupVol(space, c(1:100))
coords(ilv, 1)  # Extract coordinates for index 1
