Find Breaks for nifti Image Plotting

Helper function for plotting - returns breaks for image plot function for object of class nifti

breaker(x, zlim, col, breaks = NULL)

Arguments

x	Object of class nifti
zlim	A user-specified zlim. If NULL, will calculate how ortho2 would calculate zlim
col	colors to be plotted. Only used for length(col), so can be a vector of length cols to be plotted
breaks	if !is.null(breaks), then will calculate breaks. Otherwise will return this breaks vector

Value

Vector of length 2

If breaks = NULL, then vector of length(col) + 1, otherwise returns breaks
