Hello- I apologize in advance for what is likely a newbie question, but here goes:
In the geoR package, after using dup.coords to identify co-located data points, is there an easy way to delete duplicate observations? If it makes things any easier, my duplicate observations/co-located points are adjacent in the dataset. For example, the command dup.coords(spadata) dup longfix lat data 977 1 -87.79917 42.14 0.0443 978 2 -87.79917 42.14 0.0352 And to be a bit more specific, rather than deleting duplicate observations outright, I would prefer to establish some sort of criteria for removal of duplicates - in the above case, I would like to keep the observation with the larger data value. Of course, if this isn't possible, I'd be happy with any method to delete duplicates, and I can deal with the selective deletion through a prior sort. Any help would be much appreciated!
