Extract Coordinates from an IndexLookupVol Object

Source: R/index_vol.R, R/roi.R, R/sparse_neurovec.R
coords-methods.Rd

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

Usage

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

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

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

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

# S4 method for class '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
#>      [,1] [,2] [,3]
#> [1,]    1    1    1
