[R] sort order of a character sequence is different on windose and linux (linux result)

[Witold E Wolski]

This is the info I got from the data.table developers... Seems that
they did have tried to find a more elegant solution solution.:


data.table used to support this until 1.8.6. But since Scollate became
not a part of authorised R-API (IIUC) anymore at some point,
data.table only supports sort/order under the C-locale.

data.table's ordering/sorting is over 10-20x faster than base's and
the only way right now (IIUC) to sort by locale is to use base's
sort/order.

This post may give some more insight.

In summary, we support only C-locale.
