# S3 method for nifti
mean(x, ..., mask)

# S3 method for anlz
mean(x, ..., mask)

Arguments

x	Object of class nifti
...	Arguments passed to mean.default
mask	object to subset the image. If missing, then all values of the image are plotted.

Value

Output of mean

Examples

img = nifti(array(rnorm(10^3), dim = rep(10, 3)))
mask = img > 0
mean(img, mask = mask)
#> [1] 0.834495
