There is only one existing method available for the
bufferedTract generic function, which will generate valid
objects of class
signature(bufferWidth = "numeric", tract = "Tract")
This method takes the form shown below...
bufferedTract(bufferWidth, tract, runQuiet = FALSE, ... )
bufferWidth: The width of the buffer in the
correct units. For "English" units, this would be feet, for
"metric," meters. The buffer must be smaller than the tract extents.
tract: A valid tract object to which we
will add the internal buffer.
