Although it is the attempt to load lattice that triggers the fault, the difficulty actually reported was with loading the 'grid' Namespace. The grid package is one of the core R packages, so I have two suggestions:

First try to load grid as a package. (Although it's a core R package, it is not automatically loaded when R starts.)

library(grid)

If that fails then you clearly have a broken installation of R, and would need to reinstall. If it doesn't fail, then the error message would seem to be a puzzle, and you should re-read the Posting Guide and follow the instructions on reported unexpected behavior which you have so far only followed very incompletely.
