Hi,
I have noticed that saving data to files that include a DBF, result in
bogus data where there were NA. Using the write.dbf() function from
the foreign package seems to work a little better, but I still get odd
results in numeric columns. Writing to GRASS with the methods in the
spgrass6 packag

My problem is that I can't import precise (to 3 decimal places) Northing and
Easting coordinates into R. The data were taken on a ProMark3 GPS unit,
with the intent of obtaining extremely precise GPS coordinates.
Post-processing was done correctly, and the resulting Northings and Eastings
were to
