[R] Sweave recode(car) and Lyx, compiling but not executing on Mac

[Graham Smith]

While this is a bit embarrassing , it seems I had two problems, one
was that the recode command seems to need utf8 coding rather than the
Lyx default (which is fine), plus I had typing error in the data set,
which is not fine :-(.

I rewrote my code using the with command which allowed it to run, but
it then became obvious that the recoded resuts were not what I had
expected. The typing error then being obvious.

The first entry in my rcode was 'X2001'='2001' but the first level in
the data set was "X20001" and this was enough to cause recode to fail
in my original code, but run using the with command.

Its now working.

Thanks to everyone for there help.
