Hello all: I checked inside most of the R spatial analysis packages, without success, so I'll ask the list:
I have a set of data collection points georeferenced with lat/long coordinates. The task is to find the closest (in lat/long) matching point in a second set of points (polygon centroids, that I created with R get.Pcent() function). both point sets are stored in data frames, I would like to record the index of the matching point as a new column on the first data frame. Is there an existing R function or package that would support this, or get close? Thanks for any assistance. Thanks, Rick R -- Rick Reeves Scientific ProgrammerAnalyst National Center for Ecological Analysis and Synthesis (NCEAS) University of California, Santa Barbara [EMAIL PROTECTED] 805 892 2533 _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
