the example() function seems to have a bug.  Specifically commands such 
fail, even though there is a layout example.   The problem seems to be 
that the example function tries to open (in this case) layout.show.R 
instead of layout.R.

I think this is because the example function is looking at the first 
column of the AnIndex file instead of the second column.  If one 
        file <- system.file(paste("R-ex", directory.sep, 
                                  AnIndex[2 * i], ".R", sep = ""), pkg = pkg, 


        file <- system.file(paste("R-ex", directory.sep, 
                                  AnIndex[2 * i+1], ".R", sep = ""), pkg = pkg, 

it seems to work for me. (Note the fix has [2 * i + 1])
