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")
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);
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!
