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!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
