Hi:I like use R for data mining, organization, manipulation and mapping of SSURO data of USA. I have already done first two; I need help for mapping these data.in R It will be appreciated if someone helps me to solve following three issues:
*1. How do I merge several shape files?*I like to merge several shape files to create a single shape file. All files are same structure but different names and in different folders. Below I mentioned how all shape files are organized in different folder. I want to write a function that I can use to merge the shape files.
*File organization:* .../State_name/soil_ia001/spatial/file_name01.shp .../State_name/soil_ia003/spatial/file_name03.shp .../State_name/soil_ia005/spatial/file_name05.shp . . .../State_name/soil_ia21/spatial/file_name21.shp *DBF file associated all shape files look like below: * ID AREASYMBOL SPATIALVER MUSYM MUKEY1 IA001 2 822D2 402210 2 IA001 2 24C2 402161 3 IA001 2 93D2 402217 4 IA001 2 W 1857266 5 IA001 2 W 1857266 6 IA001 2 370C 402177 7 IA001 2 570B 402190

2. My second question is: I like to join a table with this above
mentioned shape using a conmen ID like MUKEY. How do I do this?*
*3. My third question is: how do I convert this shape file to a
grid (as a TIFF format or others? ) that I open some other software?*
Thanks Zia
