sumcpp R Documentation
Sum of Vector Elements (C++)
Description
This function uses the accu() function from the Armadillo library, a C++ library for linear algebra and
scientific computing. For double-Precision vectors, the run time of this function is faster than the base
sum() function, making it better suited for summing the weight variable with > 3000 elements.
Usage
sumcpp(x)
Arguments
x
A numeric vector.
Value
A numeric vector.
Examples
# Summing a double vector
x <- runif(1000000, 0.0000001, 1.99999999)
sumcpp(x)
