Integers are more room effective. The code under compares the dimensions of an integer this vector to a normal numeric link vector:

Rcpp sugar brings an increased-standard of abstraction to C++ code penned utilizing the Rcpp API. What This implies in exercise is we could publish C++ code while in the form of R. Such as, suppose we wished to find the squared variance of two vectors; a squared residual in regression. In R we would use
