Dear useR's,<br><br>After I found Rcpp a few days ago, I've been very excited collecting documents for learning. But still I find myself understand little.<br>Here's a question I want you to help me with.<br><br>
In page 17 of Dirk and Romain's slides from part2 of the Apr 28 Rcpp workshop (here's a link: <a href="http://dirk.eddelbuettel.com/papers/rcpp_workshop_part_2_details.pdf">http://dirk.eddelbuettel.com/papers/rcpp_workshop_part_2_details.pdf</a>), I can't figure out why the two examples behave differently.<br>
And also, why are people using 1L:3L? What not just 1:3?<br><br>Maybe I am asking silly question? But please do help me. I couldn't find an answer on google.<br>Thank you.<br><br>Best,<br>Zhongyi<br><br>
