From what I gather, after installing an R package, one needs to restart

Yikes! Turns out that...
{{{
## <entry>
## Deprecated in 1.6.0
## Defunct in 1.7.0
machine <- function() .Defunct()
Machine <- function() .Defunct(".Machine")
Platform <- function() .Defunct(".Platform")
restart <- function() .Defunct("try")
## </entry>
}}}
Note that R is now at version 2.10.1! So this is the problem here. The
restart() thing must be very old - and odd, since the function that
replaced it was try (for exception handling. Anyway, if reset() is good
enough, that is fine - no need to do r.foo() if a normal Sage command does
it well enough. I'll work on a patch for this.
