Assuming that this dataset fits within the confines of R, this could be
done with sp package: spdistsN1() function
See attached sample solution:

Hope this helps! RR

It seems that a raster-based approach would make more sense, rather than
the hugely computationally inefficient approach you are suggesting --
how about using a least cost path or euclidean distance approach? Both
are available in many GIS packages (ArcMap, GRASS GIS, etc...)

Dear r-sig-geo,
I would like to generate random points within each of several polygons. I would
like for the sample size of each point sample to be different for each polygon.
I would then like to overlay a grid or raster to visualize these point over the
entire study area. In other words have
dear all,
I have a raster GIS map converted to points. Now, I am trying to calculate
the nearest neighbor distance for every point to a cluster of points within
this map. Since the number of points is more than two millions, I am
wondering whether there is a computation efficient way to do this.
Dear R Users and Thanks Tomislav
My problem is in this RSAGA module to load all file "_10" (_11, _12, _13)
and merge together
The real data-base has not an order name and I have more over 100 files
