nearest_pts

Finds the nearest non-missing neighbors of a target point in a 2D matrix

internal

A 'ggplot2'-consistent approach to generating 2D displays of  volumetric brain imaging data.
Display data from multiple NIfTI images using standard 'ggplot2' conventions such scales, limits, and
themes to control the appearance of displays. The resulting plots are returned as 'patchwork' objects,
inheriting from 'ggplot', allowing for any standard modifications of display aesthetics supported by 'ggplot2'.
