,@JamesToll: As always, it depends. See eg gallery.rcpp.org/articles/si… -- it can be very close. Rcpp sugar helps, as do proper abstractions.

.@hadleywickham See cran.r-project.org/bin/windo… -- it is BOOSTLIB here.

.@hadleywickham: It is "permitted" as some packages have used Boost for ages, incl my RQuantLib. There is even an env var in Windoze.

Thanks @hadleywickham --- please feel free to contribute some too. The Rcpp Gallery is meant for user contributions! #rcpp #rstats
.@hadleywickham Still don't get your point: '1:3 == rev(3:1)' works, but compares each element. So wrap all() around. Or use identical.
1
.@hadleywickham Your abuse of terminology,. I'd call identical() a "bitwise object comparison". Of any R type.
1
.@hadleywickham: counter-example: identical(1:3, seq(1,3)). There is still no scalar in R. #rstats

.@kevin_ushey The real power lies in using them at the C++ level, making the C++ code more concise and expressive.

I am not sure this is a good idea. MT @kevin_ushey Speed up your R session with RcppSugar. github.com/cdrv/RcppSugar drop-in C++ replacements

.@kevin_ushey They usually end up getting their deserved punishment: think 'less than' comparison to a negative number sans spaces ;-)
