[datatable-help] CJ behavior in 1.7.5

[Matthew Dowle]

That works fine for me. The NAs look like the problem in 1.7.4 that was
fixed.  Which version of R?  If it's windows please restart all R
sessions to make sure 1.7.5 is installed and loaded cleanly (he says
clutching at straws)?  The previous post about CJ also looks fine to me
in 1.7.5.
