Is there any function such as rangesearch but for one point only knowing the max distance (radius ) to find the next point?

There are functions that will calculate all inter-point distances for you, but those will calculate all (after which you can filter valid ones).
Do you want only a single point from many? Then it might be faster to have a loop that breaks once a valid point is found.

Read about knnsearch.

can you not just use rangesearch, and use a Y variable that has only 1 observation (1 point)?
