[R-sig-Geo] error in readShapePoly

[Mahbubeh Parsaeian]

Dear all
I have a shape file of UK. I have used it serveral times before. But now when I want to use this shapefile the following error will apear.


shp<-readShapePoly("GreaterLondon_ward")
Error in read.shape(filen = fn, verbose = verbose, repair = repair) : 
  File size and implied file size differ, consider trying repair=TRUE


shp<-readShapePoly("GreaterLondon_ward", repair=TRUE)
Error in read.shape(filen = fn, verbose = verbose, repair = repair) : 
  Cannot repair file size error


If it is possible please let me know what is the problem.
Best
