[R-sig-Geo] shapefiles + plot

[Leons Mwenda]

Dear all, 
 I need to performe universal kriging using ancillary data. Dependent data 
(variable) is irregular data in projected coordinates. Secondary data 
(independent variable) is image in geographical coordinates system. The problem 
is I am getting error when projecting image that of torrelance exceeds limit. 

Help to fix this

That is one way, but readOGR can read all sorts of geographic data
and can get complicated. You might want to try readShapeSpatial from
the maptools package.

Install maptools, then help(readShapeSpatial) will give you some examples.
