Hello
I am using the FIPS code for the joint between the county maps and the
information, but I have a problem, the county fips have a problem with data
joins with the codes like "01001" were omited cause when read by are in the
data set became "1001". I am using this set code to make the join, if
someone uses or do something different, please let me know.

 #### if you want to keep all polygons
    tab <- tab[match(shpID,tabID),]
      # matches both IDs and replaces nomatch values by NA
    rownames(tab) <- shpID
    shape.mod <- spCbind(shape,tab)


Thanks
Juan
