Therefore time spent optimizing code early while in the developmental stage could possibly be wasted. Even even worse, You will find there's trade-off in between code pace and code readability; we’ve previously produced this trade-off at the time through the use of readable, (but slow) R in comparison with verbose C code!
Rcpp sugar provides a greater-amount of abstraction to C++ code composed using the Rcpp API. What This implies in follow is that we could generate C++ code inside the style of R.
