[R] Identifying clusters of size n

Is there a library which is capable of identifying distinct clusters of size n
from a series of XY coordinates?

Failing this, I'd like to be able to to something like:
Using a sliding window of size n along the x-axis I'd like to determine the
distance between the center of the points in the window and the closest point
outside the window. I could then use a distance cutoff to help define my
clusters of size n. However, how can I calculate this distance?

Cheers,
Nathan
