mean-methods: Temporal Mean of a NeuroVec

In neuroim2: Data Structures for Brain Imaging Data

Temporal Mean of a NeuroVec

Description

Computes the voxel-wise mean across the 4th dimension (time), returning a 3D DenseNeuroVol or SparseNeuroVol.

Usage

## S4 method for signature 'DenseNeuroVec'
mean(x, ...)

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

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

Arguments

x	A NeuroVec object.
...	Ignored.

Value

A NeuroVol containing the temporal mean at each voxel.

Examples

bspace <- NeuroSpace(c(10, 10, 10, 20), c(1, 1, 1))
dat <- array(rnorm(10 * 10 * 10 * 20), c(10, 10, 10, 20))
vec <- DenseNeuroVec(dat, bspace)
mean_vol <- mean(vec)
dim(mean_vol)  # 10 10 10
