[datatable-help] cedta decided 'igraph' wasn't data.table aware

[Sam Steingold]

Hi, what does this mean?

--8<---------------cut here---------------start------------->8---
> graph <- graph.data.frame(merged[!v,], vertices=ve, directed=FALSE)
cedta decided 'igraph' wasn't data.table aware
cedta decided 'igraph' wasn't data.table aware
cedta decided 'igraph' wasn't data.table aware
cedta decided 'igraph' wasn't data.table aware
cedta decided 'igraph' wasn't data.table aware
--8<---------------cut here---------------end--------------->8---

`merged' and `ve' are `data.table' objects, and thus `data.frame' objects too.
the igraph function graph.data.frame accepts data.frame.
other than the messages (controlled by datatable.verbose), the code
appears to work.

Bill Dunlap kindly explained that
>> cedta ("Calling Environment is Data.Table Aware")
>> is a private function in package:data.table

could you please offer more detail?
what doe the message mean?

Thanks.
