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!

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
