seeking the wisdom of the perl monks ...

within R i submit this code: 

> data <- c("2016-03-15 13","2016-03-16 23","2016-03-17 06","2016-03-1
+8 15","2016-03-19 08","2016-03-20 21")
> datevec <- strptime(data,"%Y-%m-%d %H")
> difftime(datevec[-length(datevec)],datevec[-1],units="hours")

[download]
which correctly produces this output:
Time differences in hours
1 -34 -7 -33 -17 -37

notice the two lines. now, in perl i have this code:
$R->set( 'data', "2016-03-15 13","2016-03-16 23","2016-03-17 06","2016
+-03-18 15","2016-03-19 08","2016-03-20 21" );
$R->run( q`datevec <- strptime(data,"%Y-%m-%d %H")` );
$R->run( q`xx <- difftime(datevec[-length(datevec)],datevec[-1],units=
+"hours")` );
@Rres = $R->get('xx');
print Dumper(\@Rres);

[download]
which correctly produces this result:
$VAR1 = [
          [
            'Time',
            'difference',
            'of',
            'hours'
          ]
        ];

the problem is that no matter what i do i cannot get to the second output line from R ... the line 1 -34 -7 -33 -17 -37

any suggestion on how i can get to the second (and in many cases n-number) of subsequent output lines from R? thanks!
