concat: Concatenate two objects in the time dimension

Description

Concatenate two objects in the time dimension

Usage

concat(x, y, ...)
# S4 method for NeuroVec,NeuroVol
concat(x, y, ...)
# S4 method for NeuroVol,NeuroVec
concat(x, y, ...)
# S4 method for NeuroVec,NeuroVec
concat(x, y, ...)
# S4 method for ROIVec,ROIVec
concat(x, y, ...)
# S4 method for DenseNeuroVol,missing
concat(x, y, ...)
# S4 method for DenseNeuroVol,DenseNeuroVol
concat(x, y, ...)
# S4 method for AbstractSparseNeuroVec,missing
concat(x, y, ...)
# S4 method for SparseNeuroVec,SparseNeuroVec
concat(x, y, ...)

Value

A temporally concatenated object.

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.

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
