in reply to Entire Results from R

Your use of \$R->set() is incorrect: to set multiple values, you have to pass an arrayref: \$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"] ); Then the code works for me.

++haukex I put together a short script to confirm that your solution works (I was curious about Statistics::R since I had not used it before). This code,
```#!/usr/bin/env perl

use Statistics::R;
use Data::Dumper;

# Create a communication bridge with R and start R
my \$R = Statistics::R->new();

\$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);

exit;
Gives this output,
```\$VAR1 = [
[
'[1]',
'-34',
'-7',
'-33',
'-17',
'-37'
]
];
