[datatable-help] Time to delete J?

[Matthew Dowle]

Hi Ken, 

Indeed. It's removed and noted in 1.8.7, just not on CRAN
yet : 

o The J() alias is now removed *outside* DT[...], but will still
work inside DT[...];
 i.e., DT[J(...)] is fine. As warned in v1.8.2 (see
below in this file) and deprecated
 with warning() in v1.8.6. This
resolves the conflict with function J() in package
 XLConnect (#1747)
and rJava (#2045).
 Please use data.table() directly instead of J(),
outside DT[...].

Thanks,

Matthew

*outside* DT[...] because J() conflicts with the function J() in
XLConnect and rJava. Please use data.table() instead, or define an alias
yourself. J() will continue to work *inside* DT[...] as documented. This
warning is issued from v1.8.3. J() will be unavailable for use outside
DT[...] from v1.8.4. Only then will the conflict with rJava and
XLConnect be resolved.")
