[R] using character vector as input argument to setkey (data.tablepakcage)

[Matthew Dowle]

Hi Sean,

Try :
   key(test.dt) = c("a","b")

Btw, the posting guide asks you to contact the maintainer of the package
before r-help. Otherwise r-help would fill up with posts about 2000+
packages (I guess is the reason). In this case maintainer("data.table")
returns "datatable-help at lists.r-forge.r-project.org" (cc'd) where you will
be very welcome.
