Hi

I have a polygon shapefile that is NAD83 and described in longitude and
latitude. I would like to create a buffer around this polygon, with the
buffer distance defined in meters.
I am using the gBuffer function from the rgeos package, but I do not know
what units the function is expecting. How can I define the units of the
distance I input?
Any help or advice would be greatly appreciated!
Thanks!
