The function stamp.multichange
is a wrapper function that makes multiple calls to the stamp
function to ease spatial-temporal analysis of multiple years of polygon data

stamp.multichange
is a simple wrapper function for the stamp
function. The two options for data structure
are those in the katrina
data, where each time period is a row, and rows are time-ordered, and the structure of
the mpb
data, where time period is specified by a column. Time periods should be ordered from 1 through T.
A SpatialPolygonsDataFrame
which includes all outputs from the calls to the stamp
function. If there are T time periods,
there will be T-1 time periods in the resulting SpatialPolygonsDataFrame
object.
