Lookup Values in an IndexLookupVol Object
Description
Performs a lookup operation on an IndexLookupVol object.
Usage
## S4 method for signature 'IndexLookupVol,numeric'
lookup(x, i)
## S4 method for signature 'AbstractSparseNeuroVec,numeric'
lookup(x, i)
Arguments
x
An IndexLookupVol object
i
A numeric vector of indices to look up
Value
the values of the lookup volume
Examples
space <- NeuroSpace(c(64, 64, 64), c(1, 1, 1), c(0, 0, 0))
ilv <- IndexLookupVol(space, c(1:100))
lookup(ilv, c(1, 2, 3)) # Look up values for indices 1, 2, and 3
