[R-sig-Geo] Read shapefile with correct proj4string for the data

[Jim Burke]

Hi I have a shapefile that I open successfully
but incorrectly (data is not in lat long format)
with the following. I am curious what the correct
proj4string would be given the "prj" file below.

my_map_sp <- readShapePoly("my_shape_file.shp",
IDvar="ID", proj4string=CRS("+proj=aea
+ellps=GRS80 +datum=WGS84"))

What is the correct "proj4string" format
given the below?

PROJCS["NAD_1983_StatePlane_Texas_North_Central_FIPS_4202_Feet",
GEOGCS["GCS_North_American_1983",
DATUM["D_North_American_1983",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]],
PROJECTION["Lambert_Conformal_Conic"],
PARAMETER["False_Easting",1968500.0],
PARAMETER["False_Northing",6561666.666666666],
PARAMETER["Central_Meridian",-98.5],
PARAMETER["Standard_Parallel_1",32.13333333333333],
PARAMETER["Standard_Parallel_2",33.96666666666667],
PARAMETER["Latitude_Of_Origin",31.66666666666667],
UNIT["Foot_US",0.3048006096012192]]

Thanks,
