[R] print.data.frame : row.name = FALSE not having intended effect

[Matthew Pettis]

Thanks Rolf,

I'm running this on Ubuntu Hardy Heron, and as far as I can tell from
http://packages.ubuntu.com/search?keywords=r-base&searchon=names&suite=hardy&section=all
, v2.6.2 is the version they have available.  The painless upgrade for
me is to use 'aptitude' to get v2.7.x, otherwise I have to build it
from scratch...

Unless you know of a repository of binaries that has v2.7.x?

Thanks,
Matt
