Read US census demographic profile data. The raw data can be downloaded in Shapefile format from http://www2.census.gov/geo/tiger/TIGER2010DP1/County_2010Census_DP1.zip to be used with this function.

1	readCensus(dsn="",layer="County_2010Census_DP1",state,fips,codes)

`dsn`	The data source name, usually a path pointing to the folder the county shapefile is in. Defaults to current directory.
`layer`	Layer name, usually the filename without the extension. Defaults to the 2010 Census data by county (County_2010_Census_DP1).
`state`	A character vector specifying which states to extract. If not specified, defaults to all states.
`fips`	A `data.frame` object with 5-digit FIPS codes as row numbers and two columns (state,county) with names of the state and county matching the FIPS code. A complete object is included in this package, see the `fipslookup` dataset.
`codes`	A lookup table for demographic profile data element to its full name. One such lookup table for age and sex demographic groups is provided with this package, see the `dplookup` dataset.

A SpatialPolygonsDataFrame. The data slot contains renamed columns of all the age and sex groups along with a 5 digit state+county FIPS column. This format is compatible for use with the getSMR function from the diseasemapping package.
