[Rcpp-devel] Presentation of Rcpp in Meielisalp

[Jonas Rauch]

Just as a remark:
As a long term R user I have to object to your use of "=" in the R code
(e.g. on page 20). There is a difference between the operator "<-", which us
usually used for assignment, and "=", although in your examples they do the
same [1].

Best regards,
Jonas
