Re: st: AW: var already defined problem
Martin,
I tried your suggestion and compared the output to a similar file, and  
I can't seem to understand what's going on.  Stata loops through once  
on the -vincenty- command, the returns the error about the haversine  
variable as already defined.
My other file is a subset of the same data as above, but input  
manually:  there are two data sets with longitude and latitude points,  
nonmatch merged, then I go right to the forv loop.  If you have  
another tip (or if anyone else does), I'd appreciate it.  In the  
meantime, I'll be pulling out my hair.
I don't understand why the manually input data would work and not the  
existing data.  Strange.
Thanks.
