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

Description

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

Arguments

x	x-position of the point whose neighbors should be found within in_mat
y	y-position of the point whose neighbors should be found within in_mat
in_mat	a 2D matrix to search for neighbors of pt
neighbors	the number of closest non-NA neighboring values to return within in_mat
radius	the radius around pt to search. Default: 8.
ignore_zeros	if TRUE, then zero is not a valid imputation value (since these are not data in NIfTIs)

Value

A vector of neighbors closest neighboring values around pt
