[datatable-help] Making data.table shiny aware or vice-versa?

[Matthew Dowle]

Adam,

Ah thanks for link. Yes that would have done it. Great.

For future reference, cedta.override is intended for calling 
environments we (or the data.table user) have no immediate control over 
(such as  gWidgetsWWW).  But if it's your environment or your package 
(and Depending or Importing data.table isn't possible) then you can set 
.datatable.aware=TRUE instead in your environment that's using 
data.table syntax. We couldn't add that to gWidgetsWWW because new 
variables can't be added to sealed environments, but we (and users) can 
change (the existing) cedta.override variable in the data.table 
namespace (being careful to add items to the existing vector) as an 
interim measure until a proper solution can be found.

Hopefully, Depending, Importing, cedta.override, and 
.datatable.aware=TRUE should cover all bases. Hadley has set 
.datatable.aware=TRUE in dplyr for example (it was his suggestion to add 
that actually, since dplyr has an _optional_ dependency on data.table).
