concat-methods: Concatenate two objects in the time dimension

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

Concatenate two objects in the time dimension

Description

Concatenate two objects in the time dimension

Usage

concat(x, y, ...)

## S4 method for signature 'NeuroVec,NeuroVol'
concat(x, y, ...)

## S4 method for signature 'NeuroVol,NeuroVec'
concat(x, y, ...)

## S4 method for signature 'NeuroVec,NeuroVec'
concat(x, y, ...)

## S4 method for signature 'ROIVec,ROIVec'
concat(x, y, ...)

## S4 method for signature 'DenseNeuroVol,missing'
concat(x, y, ...)

## S4 method for signature 'DenseNeuroVol,DenseNeuroVol'
concat(x, y, ...)

## S4 method for signature 'AbstractSparseNeuroVec,missing'
concat(x, y, ...)

## S4 method for signature 'SparseNeuroVec,SparseNeuroVec'
concat(x, y, ...)

Arguments

x	the first object, typically NeuroVol or NeuroVec
y	the second object, typically NeuroVol or NeuroVec
...	additional objects

Details

The x and y images must have compatible dimensions. a NeuroVol can be concatenated to NeuroVec, and vice versa. See examples.

Value

a temporally concatenated object.

Note

dimensions of x and y must be equal

Examples

bv1 <- NeuroVol(rep(1,1000), NeuroSpace(c(10,10,10), c(1,1,1)))
bv2 <- NeuroVol(rep(2,1000), NeuroSpace(c(10,10,10), c(1,1,1)))
bv3 <- concat(bv1,bv2)
inherits(bv3, "NeuroVec")

bv4 <- concat(bv3, bv1)
dim(bv4)[4] == 3
bv5 <- concat(bv1, bv3)
dim(bv4)[4] == 3

bv6 <- concat(bv4,bv5)
dim(bv6)[4] == 6
