In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

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 '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

The extracted coordinates corresponding to the provided index If the index is not found, it returns NA

Examples

## Not run: 
ilv <- IndexLookupVol(space, c(1:100))
coords(ilv, 1)  # Extract coordinates for index 1

## End(Not run)
