Checking mapping warning issue with FIPS #1

Closed geanders closed 8 years ago

When I try to map events for Sept. 15-20, 1999, I'm getting this warning: 

  Your data.frame contains the following regions which are not mappable: 2005, 2007, 2015, 2017, 
2018, 2022, 2024, 6018, 6042, 6048, 6056, 6080, 6082, 8036, 8038, 8040, 8066, 8070, 8072, 
8074, 12025, 12038, 12052, 12054, 12056, 12062, 12064, 12076, 12078, 15002, 15004, 15006,
 25020, 25022, 25024, 30034, 35004, 35010, 35016, 35026, 37016, 37030, 37032, 37046, 37080, 
37094, 37098, 37102, 37104, 41024, 41026, 44006, 45044, 45050, 51094, 51096, 51098, 51100,
 56012, 56014, 96010, 96020, 96030, 98006, 99013, 99069, 99113, 99123, 99127

Let's check that out. Are there fips codes that aren't really fips codes? Are they codes for counties that have changed FIPS codes since the storm data was input? Let's see how many of these we can resolve.

Here's a site through the US Census giving changes in FIPS codes since the 1970s:
